@akien-mga Sorry to flag you. Do you have an idea if this issue has been solved on 3.1/3.0/master? and/or which commit might fixed that? Or maybe I can tweak the audio mixer to fix it?

akien-mga · 2019-02-14T15:11:39Z

Do you have an idea if this issue has been solved on 3.1/3.0/master?

The best way to know would be for you to give it a try, I can't say just from the description without doing tests myself.

xsellier · 2019-02-14T15:59:25Z

The fact is, I cannot reproduce it, on any of my windows machine. But according to the sample I received, I cannot deny the issue.

I cannot know if the issue has been solved on branch 3.0/3.1 or master since I can't reproduce the issue on 2.1. I was just wondering if you've remembered having changed something related to the audio driver used by godot engine that might solve that issue.

Maybe you have an idea of where the issue might come from, like an entry point where I can start digging please.

akien-mga · 2019-02-14T16:28:17Z

Well 3.0+ use a different audio driver on Windows (~~xaudio2~~ WASAPI), so it's likely that things changed in between. The whole audio server and audio nodes have been rewritten from scratch. So I doubt anything can be cherry-picked, it would be as difficult as porting your game to 3.1 ;)

CC @marcelofg55 who might have ideas on how to debug this further.

xsellier · 2019-02-14T16:44:46Z

Thank you a lot @akien-mga <3 Hope @marcelofg55 would be able to help me even just a little bit.

Well 3.0+ use a different audio driver on Windows (xaudio2 WASAPI), so it's likely that things changed in between

Godot 2.1.5 also uses WASAPI for windows. It uses XAudio only for winrt.

Im gonna try switching from WASAPI drivers to RtAudio drivers.

marcelofg55 · 2019-02-15T12:31:11Z

Hi, so to who is this happening? Some Windows users? It's a bit a complicated to solve if we can't reproduce this, maybe try to find out what audio card are they using, what sample rate and if they're using stereo or 5.1.
Also, does this happens with any music? or some music files only?

xsellier · 2019-02-15T14:21:29Z

@marcelofg55 Hey, I replaced WASAPI with RtAudio, it fixed the issue.

User who have the problem has a surround headset. I suggest to replace the default driver for godot 2.1.5 for RtAudio instead of WASAPI

marcelofg55 · 2019-02-15T16:24:11Z

@xsellier Can you find out what Surround Headset is the user using? Thanks

xsellier · 2019-02-15T16:34:03Z

@marcelofg55 I don't have the exact model, but it is a wireless Bluetooth surround headset.

Sound card is a Realtek High Definition Audio.

@xsellier So I've been trying to reproduce this myself without much luck, tried with my external 5.1 sound card setting it to 5.1, 7.1 and 3.1 and I've got no distortion on the sound, even tried some Surround Virtual software and no luck.
Do you know if the user experienced this bug on any music file?

I think that this bug should also be present on the 3.0/3.1 branch since the WASAPI driver uses the same logic to output sound, but until I'm able to reproduce it and can't be sure of this.

xsellier · 2019-02-15T20:48:27Z

Any music file and even with FX sound.

xsellier · 2019-02-24T21:48:41Z

@marcelofg55 This issue won't happen on the latest version of godot 3+ because of that:
https://github.com/godotengine/godot/blob/2.1/drivers/wasapi/audio_driver_wasapi.cpp#L159

So I wonder why it is like that and not as following:

	switch (wasapi_channels) {
		case 2: // Stereo
		case 4: // Surrounf 3.1
		case 6: // Surround 5.1
		case 8: // Surround 7.1
			channels = wasapi_channels;
			break;

xsellier · 2019-03-14T17:17:34Z

Bump @marcelofg55

marcelofg55 · 2019-03-15T11:48:58Z

@xsellier Unless we find a way to reproduce this I don't see a way to fix it.

xsellier · 2019-03-15T12:40:11Z

@marcelofg55 It happens only on version 2.1.5 because WASAPI in version 2.1.5 does not handle surround system. (more than 2 channels):
https://github.com/godotengine/godot/blob/2.1/drivers/wasapi/audio_driver_wasapi.cpp#L159

marcelofg55 · 2019-03-15T12:51:42Z

@xsellier I tested this with a 5.1 surround system myself and the distortion didn't happen to me. Could you reproduce the distortion using a surround system?

xsellier · 2019-03-15T13:10:14Z

@marcelofg55 I don't have a surround system at home.
I have one player (who reported it, it might have more than one) who has the issue, on release build, with a surround system as described in the first message.

But I'm wondering if it cannot come from that part:
https://github.com/godotengine/godot/blob/2.1/drivers/wasapi/audio_driver_wasapi.cpp#L159

Because on master/3.0/3.1 it looks like that:
https://github.com/godotengine/godot/blob/master/drivers/wasapi/audio_driver_wasapi.cpp#L323

Which is not the same algorithm.

marcelofg55 · 2019-03-15T13:17:20Z

@xsellier Well, I tested it on my 5.1 surround device and couldn't reproduce it, so unless somebody else finds a way to reproduce it I don't think I can find a fix for this.

But I'm wondering if it cannot come from that part:
https://github.com/godotengine/godot/blob/2.1/drivers/wasapi/audio_driver_wasapi.cpp#L159

Because on master/3.0/3.1 it looks like that:
https://github.com/godotengine/godot/blob/master/drivers/wasapi/audio_driver_wasapi.cpp#L323

Which is not the same algorithm.

Godot 3.0+ supports surround audio on the audio server, Godot 2.1 doesn't, so that's why that code is different. Anyways, I don't thins is the problem of the distortion, but since I can't reproduce it myself I can't be sure.

xsellier · 2019-03-15T13:28:45Z

@marcelofg55 Thank you for that explanation.
Maybe this informations will help you.
Whenever a player has an audio issue, I suggest him to switch to RtAudio driver (using -ad RtAudio) and it solves the issue.

xsellier · 2019-06-05T22:36:21Z

I have run into similar issue with the recent master while checking in wine my result of cross-compilation.

Favorlock · 2020-04-10T21:27:41Z

I as well am running into an issue that appears to be related to this. I get the error: W 0:00:02.221 init_render_device: WASAPI: Unsupported number of channels: 1
<C++ Source> drivers/wasapi/audio_driver_wasapi.cpp:330 @ init_render_device()

I'm using a steelseries wireless headset and I believe the receiver is connected over usb.

Mkneeshaw · 2021-01-11T11:38:13Z

I am getting this same issue using a SteelSeries wireless headset.
W 0:00:00.363 init_render_device: WASAPI: Unsupported number of channels: 1

xsellier · 2021-01-11T14:13:23Z

@Mkneeshaw Please open a new issue as this appears to be unrelated to OP's setup.

In fact this is exactly the same issue (see this comment: #25875 (comment) )

akien-mga · 2021-10-25T09:42:44Z

So it sounds like it's not 2.1 specific in the end.

@Favorlock @Mkneeshaw What Godot versions did you experience this with? Is it still reproducible with latest 3.3 and 3.4 releases?

xsellier · 2021-10-25T10:18:43Z

Fixed that issue with this commit:
xsellier@e61f7ce#diff-4a9fdda300c1d48d4e2a55d7d7810adc44efd8c75a2f74c39018d3cec3dc463c

Mkneeshaw · 2021-10-31T01:47:28Z

I have this issue still with 3.3.3 and 3.4 rc2

KoBeWi · 2022-06-08T11:10:37Z

I have the issue with this warning (not sure if it's the same as the original):

WARNING: WASAPI: Unsupported number of channels: 1
   at: AudioDriverWASAPI::init_render_device (drivers\wasapi\audio_driver_wasapi.cpp:328) - WASAPI: Unsupported number of channels: 1

The issue is that when you have bluetooth headset, it usually has 2 audio modes. One with only sound and one with sound + microphone. You can find more info here: https://answers.microsoft.com/en-us/windows/forum/all/headset-vs-headphones/93aca8a3-626c-4439-ab9f-8f774d76be44
The issue is that in the "microphone" mode, audio quality drops. You can hear it in any game/application, but in Godot the difference is just extreme, to the point that the game is unplayable with distorted audio.

Here's vide with normal audio:

godot.windows.opt.tools.64_rCwGpHbcGG.mp4

And here is the other audio mode:

godot.windows.opt.tools.64_WWvL4b4Okk.mp4

The character's voice is especially distorted. It gets even worse when you enable music:

godot.windows.opt.tools.64_XNr41XgWMS.mp4

vs

godot.windows.opt.tools.64_TN0w2uCmEh.mp4

There is this crackling noise that's just unbearable.

I don't know if there is something that can be done about it, as it might be some WASAPI problem. I know that in other games (non-Godot) the sound doesn't become completely illegible like this, so there is room for improvement.

Calinou · 2022-06-08T14:14:30Z

@KoBeWi Can you reproduce this if you change the output mix frequency to 44100, 48000 or even 22050 in the Project Settings?

KoBeWi · 2022-06-08T14:21:40Z

48000 and 22050 don't seem to make difference, with 441100 there is no sound at all (so I guess it fixes distortions? 😂).

Calinou · 2022-06-08T14:53:59Z

48000 and 22050 don't seem to make difference, with 441100 there is no sound at all (so I guess it fixes distortions? joy).

I meant 44100 instead of 441100, sorry. I guess 44100 is the default value already though.

KoBeWi · 2022-06-08T14:57:43Z

Right. I just added 0, so actually it was 441000.
But it doesn't seem to be related to mix rate anyway.

mdarcy · 2022-08-26T03:53:26Z

Hey. I, too, am experiencing this problem. Any updates?

Calinou · 2022-08-26T18:16:15Z

Hey. I, too, am experiencing this problem. Any updates?

We don't know the exact source of the problem yet, so there is no ETA for fixing this.

We did suspect however that Godot not handling mono audio output well on Windows could be a possible culprit, but this may be unrelated. (Using microphone mode on a Bluetooth headset will force audio output to be mono in many cases.)

akien-mga · 2023-04-27T21:25:18Z

Reposting my comment from #76504 (comment):

The WASAPI driver doesn't seem to implement mono audio indeed. This might just be an oversight.

Relevant code (in master, but it's likely similar in 3.x and 3.5):

godot/drivers/wasapi/audio_driver_wasapi.cpp

Lines 482 to 494 in 352ebe9

    
           switch (audio_output.channels) { 
        
           	case 2: // Stereo 
        
           	case 4: // Surround 3.1 
        
           	case 6: // Surround 5.1 
        
           	case 8: // Surround 7.1 
        
           		channels = audio_output.channels; 
        
           		break; 
        
           	default: 
        
           		WARN_PRINT("WASAPI: Unsupported number of channels: " + itos(audio_output.channels)); 
        
           		channels = 2; 
        
           		break; 
        
           }

Likewise for macOS's coreaudio driver:

godot/drivers/coreaudio/audio_driver_coreaudio.cpp

Lines 105 to 117 in 352ebe9

    
           switch (strdesc.mChannelsPerFrame) { 
        
           	case 2: // Stereo 
        
           	case 4: // Surround 3.1 
        
           	case 6: // Surround 5.1 
        
           	case 8: // Surround 7.1 
        
           		channels = strdesc.mChannelsPerFrame; 
        
           		break; 
        
           	default: 
        
           		// Unknown number of channels, default to stereo 
        
           		channels = 2; 
        
           		break; 
        
           }

While pulseaudio handles mono and other odd channel counts, apparently by just adding + 1:

godot/drivers/pulseaudio/audio_driver_pulseaudio.cpp

Lines 203 to 223 in 352ebe9

    
           switch (pa_map.channels) { 
        
           	case 1: // Mono 
        
           	case 3: // Surround 2.1 
        
           	case 5: // Surround 5.0 
        
           	case 7: // Surround 7.0 
        
           		channels = pa_map.channels + 1; 
        
           		break; 
        
           	case 2: // Stereo 
        
           	case 4: // Surround 4.0 
        
           	case 6: // Surround 5.1 
        
           	case 8: // Surround 7.1 
        
           		channels = pa_map.channels; 
        
           		break; 
        
           	default: 
        
           		WARN_PRINT("PulseAudio: Unsupported number of output channels: " + itos(pa_map.channels)); 
        
           		pa_channel_map_init_stereo(&pa_map); 
        
           		channels = 2; 
        
           		break; 
        
           }

That likely wouldn't be enough here though, because in this case it's basically what happens (1 channel is unsupported, so it falls back to 2 / stereo).

The mono output basically just needs to be implemented. The downsampling done in the PulseAudio driver could probably be ported to WASAPI.
