Sound issues (maybe ALSA related?)
I've been struggling with sound stuttering for a while with my system in general. I have to run
pw-metadata -n settings 0 clock.force-quantum 1024 every time I boot, which helps enough to use the system, but doesn't solve the issue.
Related - I was playing Clone Hero as an app installed from the AUR to an Arch distrobox. The sound issues aren't worse, but they're more noticeable and distracting considering it's a rhythm game. In order to try to help the problem, I downloaded the Clone Hero tar and tried running it directly on Bazzite. The sound issues remained the same, except a new issue cropped up where the game will sometimes completely stop audio playback. The game itself isn't frozen, because it's still rendering the note highway and I can interact with the game (pause, pick a new song, etc).
Clone Hero shows up as an ALSA audio stream, so this might be related somehow? It's the only application I use that loses all audio, but all applications exhibit the stuttering. I can pull any logs to help, just let me know. For reference, I never had this issue on Arch, Tumbleweed, Silverblue, or Windows. 😦

is this bazzite or bazzite-deck?
Oh, good question. Standard bazzite:stable
So we change almost nothing about pipewire/wireplumber on those builds, but we do ship system76-scheduler which sets nice values
perhaps it's somehow related on your setup
can you try
systemctl disable com.system76.Scheduler.service
and then reboot and see if you still get the sutters?
we can deal w/ the alsa one separate
if you do, other things we can try
note that the reboot is needed to ensure none of your current nice values have been touchedmakes sense. rebooting.
scheduler is disabled, verified by
systemctl status, still getting some stutters, but it seems to be better, and I didn't have to run the force-quantum command.
trying to reproduce the Clone Hero thing.
1) system76 scheduler on, force pipewire quantum to 1024, moderately frequent stutters
2) system76 schedule off, no force quantum, roughly the same amount of stutter
3) scheduler off, force quantum to 1024, much less frequent stutters. still present occasionallyhmm, not related to system76 then from the sound of it
I have an idea, I'll ping you when next build is out
well, it got better when I turned the scheduler off because I got the same amount of stutters without forcing the quantum, whereas when the scheduler is on, I have to force quantum for the sound to be bearable at all.
Yeah, but that doesn't explain why it's different from stock fedora
Likely just a factor
oh, true.
and I'm not scared to rebase to testing if it will help in any way.
Appreciate that, I'm building on testing now so hopefully no hiccups
interesting, about to reboot and test.
alrighty, haven't reproduced the full clone hero audio loss yet. stutters are much improved, but still there a bit. still have to force quantum to 1024 and run Clone Hero with PULSE_LATENCY_MSEC=30. but it's definitely improved.
@Kyle Gospo So with the system76 scheduler on, pipewire quantum forced to 1024, pulse latency set to 30 msecs, and TuneD profile set to latency-performance, I get almost no stutters. Maybe one every 2 or 3 minutes, which is fine.
It's still weird I don't have this issue on other distros, but I like Bazzite enough to deal, for now.
I lied, full audio drop has happened twice in the past hour now. D:
no clue what's up at this point, desktop image has no audio changes from stock fedora outside of s76
I will double check to confirm that
I've got a second hard drive, I'll install stock Fedora and test. I didn't have this problem on Silverblue, but that was also back on 36 or 37.
It's been a while.
Thread necro, but I figured it out. I reformatted back to Arch and everything was absolutely fine. Then I started trying to rebuild the bazzite experience (minus atomicity, obviously). After installing
linux-fsync-nobara-bin kernel from the AUR, I started experiencing the exact same audio issue. So it seems to be a problem with either fsync or some other flag in the nobara/bazzite compilation process. Reverting back to vanilla Arch kernel fixed it.
Might do some digging into the kernel differences when I have more time this weekend.
@Kyle Gospo in case you were curious.:clueless: so this may also be the reason I occasionally also get those audio stutters uh?
I get audio stutters suddenly - I’m using kodi and it’s really noticeable when there is music in the background - more so than speech. It is constant. Any tips?
Was working fine for about 3 weeks prior
Never mind it was isolated to just kodi - using stremio now with plugins
actually happens on steam too, stutters like mad, but moonlight streaming is fine... i guess it just hates not streaming audio for me 😄
Might be something odd-ball with system76-scheduler on your setup?
i tried the disablement of that
try
systemctl disable com.system76.Scheduler
and then reboot
hmm, ok, not that
hold on
cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_driver
what's the output of that?No such file or directory heh
wat
what CPU you using?
12600k but it’s virtualized, perhaps I should try pinning the cpus
ah that might explain it
I was looking to see if you were using pstate or acpi-cpufreq
if i had to guess, you're currently locked to the powersave governor, because tuned thinks you're using p-state
try this:
It’s using qemu backend with unraid and I have certain CPU selected (6 cores and it doesn’t seem to be constrained at all) but have not tried pinning
tuned-adm profile virtual-guest
try thatWell one thing is for sure if I try to slide power from balance to performance it won’t budge heh
Ok
if that works,
sudo nano /etc/tuned/ppd.conf
and change balanced=balanced to balanced=virtual-guest
so it defaults to thatNah unfortunately - it’s probably something wonky on backend but I’m scratching my head as to what changed haha
weird 😦
I can stream same game from moonlight and all good heh. It’s alright I’ll keep digging or rebuild. Ya know you can’t just build Linux once and be done (not blaming bazzite for issue though, i bet it's something silly with unraid)
@Kyle Gospo i'm experimenting with pulse audio settings now -- i see reference to daemon.conf but i don't see this file, do I need to create it?
if you're looking in /etc it may be in /usr/share or /usr/lib
and yes you can make it
