Hi all, after updating my desktop to KDE/KF/Plasma 6, I noticed that Elisa would not play anything anymore. The console output was something like: [opus @ 0x55f9ca4e5ec0] Could not update timestamps for skipped samples. "QAudioSink: snd_pcm_hw_params_set_format: err = -22" [ogg @ 0x7feb3000cbc0] 4979 bytes of comment header remain "QAudioSink: snd_pcm_hw_params_set_format: err = -22" [mp3 @ 0x7feb24004280] Estimating duration from bitrate, this may be inaccurate "QAudioSink: snd_pcm_hw_params_set_format: err = -22" Playing around a bit, I noticed that the KF5 version of Elisa sets the "vlc" USE flag by default. This is not the case for the current KF6 version (media-sound/elisa-24.05.1:6::gentoo). After rebuilding Elisa with USE="vlc" being set, it plays music again. So I suppose it simply lacks a backend? Maybe, "vlc" should be enabled for the KF6 version as well? Cheers, Tobias
If USE=-vlc does not work that would indicate a problem with dev-qt/qtmultimedia:6, no? > local use flags (searching: vlc) > ************************************************************ > [+ C ] vlc > media-sound/elisa: Use media-video/vlc for output rather than dev-qt/qtmultimedia See also elisa ebuild: > vlc?

I've just tested this myself and elisa:6[-vlc] with dev-qt/qtmultimedia:6[ffmpeg] (in my case) is playing audio just fine.
I just tried again. I have dev-qt/qtmultimedia:6[ffmpeg] installed. elisa:6[-vlc] doesn't play anything, yielding the errors posted above. elisa:6[vlc] works. How can I help to debug this?
Good question. Please provide emerge --info for starters. - full dev-qt/qtmultimedia:6 USE flags? - media-video/ffmpeg version, USE flags?

fwiw I can't reproduce either, I thought it *could* be related to USE=-gstreamer (default on plasma profiles) but elisa still plays audio fine even if I disable it (was using pipewire).
(In reply to Ionen Wolkens from comment #6) > fwiw I can't reproduce either, I thought it *could* be related to > USE=-gstreamer (default on plasma profiles) err scratch the default comment, forget it only set that on :5, albeit in my case it was enabled because I combine gnome and plasma profiles
Given the "QAudioSink: snd_pcm_hw_params_set_format: err = -22", I would assume something is going wrong while it's trying to use alsa (snd_pcm_hw_params_set_format is alsa). Not sure if it tried pulseaudio first and fell back to alsa, or uses alsa by default when USE="alsa pulseaudio". In theory alsa should be fine if you have pulse or pipewire alsa plugins setup fine though. You could try disabling USE=alsa on qtmultimedia to see if pulseaudio backend works. vlc may have different priorities and bypass whatever is setup wrong or broken.
Which reminds me, I guess the alsa backend on qtmultimedia is technically experimental... I imagined it was harmless given figured pulseaudio would be prioritized if it works. Guess could consider silently disabling USE=alsa when pulseaudio is enabled if it's causing problems.
I just tried dev-qt/qtmultimedia:6[-alsa] in combination with media-sound/elisa:6[-vlc]. In this case, Elisa does play music!
(In reply to Tobias Leupold from comment #10) > I just tried dev-qt/qtmultimedia:6[-alsa] in combination with > media-sound/elisa:6[-vlc]. In this case, Elisa does play music! Thanks, guess I'll change USE=alsa handling in qtmultimedia then. There may be something wrong with your alsa plugins but, either way, I don't want it to prioritize alsa plugins over using pulse directly even if they work (well, directly is relative if pipewire is used though).

Have not checked the state of this for Qt5, but probably better off not touching at this point unless someone has problems (it's possible the audio sink was going through gstreamer preventing issues).

Hey, thanks for the immediate fix :-) How would I check if something's wrong with my ALSA stuff? I think I set it up according to the wiki when I setup my machine eons ago and never touched it again ...
I guess there's not really anything pulling alsa-plugins w/ USE=pulseaudio nowadays (beside being mentioned as optfeature w/ pipewire and pulseaudio-daemon), so wouldn't be surprising if you don't have it. If using pipewire, rather than alsa-plugins, may prefer USE=pipewire-alsa on the pipewire package to have it provide its own plugin. Ultimately not essential to have unless you happen to use some applications that only support alsa. In this particular case I'd rather blame qtmultimedia for not autodetecting what it should use well.
Hey, I just wanted to update qtmultimedia, and it still wants to enable alsa, although pulseaudio is set: # emerge -1av dev-qt/qtmultimedia ... [ebuild U ] dev-qt/qtmultimedia-6.7.1-r1:6/6.7.1::gentoo [6.7.1:6/6.7.1::gentoo] USE="X alsa* ffmpeg opengl pulseaudio qml vulkan -eglfs -gstreamer -test -v4l -vaapi" 0 KiB The commit message was "dev-qt/qtmultimedia: disable alsa when pulseaudio is enabled (qt6)" -- is this intended? Apart from that I actually don't have the alsa-plugins installed.
USE=alsa (now) does nothing when USE=pulseaudio is enabled, and prints a short warning in the build.log about it. Done that way so all users that set both (which is very common being a default on plasma and gnome profiles) don't have to be forced to manually disable it as it'd be annoying. In other words, it's ok to leave it enabled and not keep configs to disable it.
Ak okay! Thanks for the explanation :-)
