No playback on one of my audio interfaces #21514

Closed HadrienG2 closed 4 months ago

HadrienG2 commented 4 months ago

Issue type

General playback bug

Bug description

My computer has several audio outputs, including a high-end USB interface dedicated to audio work, and the HDMI output that goes through the screen's built-in speakers.

At some point during the past two weeks, for unclear reasons (I can't recall anything specific that I did which might be related), MuseScore has lost the ability to emit sound through the USB interface.

If this audio output is selected, then no "echo" sound will be emitted when I input notes, and if I attempt to start playback the cursor will remain stuck at the beginning of the score like this:

However, the application is not otherwise frozen, e.g. I can stop the malfunctioning playback and input notes etc.

If the HDMI output is selected, then playback is perfectly normal. Well, by this audio output's standard at least ;)

It is not clear to me, at this stage, if this comes from a MuseScore update, an OS update, or something else entirely.

Steps to reproduce

Due to the hardware-specific nature of this bug, I unfortunately cannot provide reproducer instructions that you'll easily be able to re-run on your computer :( However, I can assist in investigating this if you tell me what to look for.

Screenshots/Screen recordings

No response

MuseScore Version

MuseScore 4.2.1, build number 240230938

Regression

Yes, this used to work in a previous version of MuseScore 4.x

Operating system

openSUSE Tumbleweed (observed on snapshot 20240212)

Additional context

The application logs contain no direct indication that any malfunction was detected in the audio stack (although it has many other warnings that you may want to investigate someday):

Although this was initially observed on a distro package, I have reproduced this on the latest AppImage from musescore.com (MuseScore-4.2.1.240230938-x86_64.AppImage) and with a blank user profile (renamed ~/.config/MuseScore to ~/.config/MuseScore.bak for the sake of experimentation). It happens both with MuseSounds and MS Basic.

Audio stack configuration: ALSA + PulseAudio

HadrienG2 commented 4 months ago

After experimenting around, one observation which may very well be related is that in several other applications including VCV Rack and Audacity, I observe similar stuck playback issues when the "wrong" ALSA output device is selected. For example, in Audacity, which uses PortAudio in ALSA mode...

Unfortunately, MuseScore's very minimal audio I/O settings do not let me pick any audio device other than "System Default", which may well map into the default device mentioned above. Not sure how, but maybe I could reconfigure ALSA/Pulse to change what default points to, since the current configuration seems wrong...

What puzzles me is that many other applications are unaffected, for example VLC (with either ALSA or Pulse output module, using either of the above audio outputs for ALSA) and Firefox can play back audio just fine. I wonder what's special about the way MuseScore, Audacity and VCV open the default output device...

I noticed something interesting in Audacity's audio device diagnostics info for the ALSA peripherals listed above:

Notice how default and pulse expose many different sample rates, whereas the hardware-specific audio output exhibits only one sample rate of 96kHz. This made me wonder if this isn't some kind of PulseAudio bug where many sample rates are exposed, but only one can actually be used?

...and indeed, if I set up Audacity to emit 96kHz sound, not 44.1kHz sound, the default and pulse devices work just fine! Looks like there's something fishy about PulseAudio's resampling functionality... I have submitted a distro bug report about this.

It would be really great if MuseScore had more audio output configuration options, so that I could experiment with this and hopefully get it unstuck...

HadrienG2 commented 4 months ago

At least I've found a workaround ;)

Turns out I'd been configuring pulseaudio with default-sample-rate = 96000 for a while because I did not want it to silently switch to 44.1kHz when I'm doing recording/monitoring at 96kHz. The problem seems to be linked to this specific configuration. With the default default-sample-rate = 44100 configuration, I cannot reproduce the issue.

HadrienG2 commented 4 months ago

Overall, with the extra info, this feels like a pulseaudio or hardware/driver bug to me, more than like a musescore bug. So I'm closing it for now. Please just take it as a reminder that audio output options matter and those of MuseScore 4 on Linux are currently too bare-bones to be useful ;)
