what could cause scratchy audio on game mode?
GitHub
The scratchy audio goes away when unplugging and plugging headphones back in
Hi have noticed this only happens if you go from gamemode to desktop mode and then back to game mode (also happens on a htpc with the deck image)
Ddoes it happen on steamos as well?
MI’m curious, we’ve just been dealing with this on several distributions on the ROG Ally. If you leave the controls alone for 15 seconds after switching from desktop to game mode, does audio fix itself?
Hnot on stock stable last time i checked, will check again as i am about to use my SD atm
Maudio is scratchy when you go from Game Mode to Desktop and back to Game Mode but it will clear itself if you leave it alone for 15 seconds after it launches. At least that’s the Ally behavior
Dgonna test it\
Mwait 15 seconds after the Steam logo with audio plays. If you navigate the UI before that point it basically starts another 15s countdown from my own testing
MIf that doesn’t fix it it’s probably separate issues then
Hdoesnt happen on SteamOS 3.4.11 at least
MI’ve only just noticed it in the past couple days. There’s a new BIOS out for ROG Ally which I thought was the cause of this, but if it’s happening on other devices that points to something like a Gamescope-session issue
Hgamescope did get some bugs yesterday-ish
Dit does fix
Mokay I’ll let the Gamescope-session devs know. thanks for checking that
MI’m on Nobara which is a mutable Fedora distribution, going to try downgrading Gamescope-session and see what happens. I’ll report back if I find anything relevant to Bazzite as well.
Mwhat devices are you using? just trying to see if it’s only a certain manufacturer or hardware part
Dsteam deck
Ha htpc i built long long long ago with an intel i5 4th gen cpu, 16gb ram and an rx560 8GB card (ends up with roughly the same performance as the deck on average but is a console and guest pc)
Hso 2 wildly different systems 
Mgot it. do you know what audio chip is in there?
Hi will try to find out
Mthanks, much appreciated
HIntel 8 series C220 according to lspci, however the audio chip being used is more likely the rx570 one as its over hdmi, that one would be Ellesmere HD Audio (no idea where to find the version for it)
Mgot it. that should be enough info.
H570, my bad its an rx570. doesnt matter though 
Hjust tested the 15 second thing, its the exact same sympthoms and fix
Malright. ChimeraOS devs manage Gamescope-session so I put this in their discord and I’ll look at Gamescope later to see if any filed issues match this one.
KInterestingly this isn't happening for me, but I'm on the Fedora 39 branch
KHopefully I'll have test images of that here soon
KIf it's as simple as that that's great news
MI was talking to two people on the exact same setup as me (same bios version and kernel) and eventually their audio distortion magically disappeared. Mine hasn’t. Very strange stuff.
RYeah, lately when opening side menus a lot of times the audio get completely mangled timing wise. It's probably just game scope. Did anyone report this on the github repo already?
ROh, it's just with headphones audio connected? It's basically always for me lately.
Mit happens over Bluetooth as well apparently
RMonitoring Steam, it seems that steamwebhelper is hammering one core after bootup for 15 seconds and if any input are applied it keeps hammering it.
RIf you wait, the load goes back down and no more audio stutters.
RYeah, matches my experience as well yesterday.
RIt might be a Steam beta bug.
RI'll do additional testing now, I can easily reproduce with sleeping/wake up cycle.
R(I'm on Deck, btw)
RIt's the whole system that's hitching, which made me think of some interrupts issues, but now I'm not that sure.
ROn Deck, the 6.5 kernel added an issue with the rtw88 driver that steals irq cycles after sleep when getting out from low power state, and I though that the two issues were linked toghether.
RIt doesn't seems that way now.
RNope, Steam settles down even with the audio issues.
RNot sure at this point from where they are coming from
RCan't really see any interrupts differences between stutter and no stutter.
RHardware are different, so no correlation with that.
RIt must be software somewhere.
RI'll check 6.5.6 for audio changes
RCan't really see other common sources for it
ROpened a pipewire issue, it's the most probable cause.
