Hi All,
To test some kernel work (backlight refactor) which I have been doing I have booted Debian Testing with a 6.0 kernel on a Sony Vaio VPX11S1E (which is ancient).
I noticed that when tab-completing something in a terminal the terminal bell sound would keep repeating and playing another longer sound sample gets stuck with the first couple of seconds of that sample looping.
This is under GNOME3 with pulseaudio as sound server.
I accidentally found an interesting workaround if I run:
aplay -Dplughw:CARD=MID,DEV=0 /usr/share/sounds/alsa/Front_Left.wav
once, then that works properly and after that the problem is gone...
Note that this laptop does have only 1 speaker AFAICT.
alsa-info output below.
I would be happy to test any patches / module-options which might fix this.
Could you check the very latest Linus tree (6.0-rc5)? There has been a regression fix for HD-audio, and possibly this might be your case.
And if this doesn't change the behavior, try snoop=0 option for snd-hda-intel module.
Thanks, I've just tried with 6.0-rc6 both with and without snoop=0 and neither helps I'm afraid.
Then one another thing could be position_fix option of snd-hda-intel. Otherwise we need bisection -- supposing it worked well in the past.
Thanks, position_fix=1 does the trick (I did not try any of the other possible values).
I see there is a snd_pci_quirk position_fix_list, so I guess I should prepare a patch adding a quirk for this?
I guess this is rather controller issue, so I'd patch for Poulsbo like below. Let me know if it works, then I'll cook a proper patch.
Or are some other position_fix values preferred and should I try those first?
LPIB should suffice, so no further test about the option needed.
thanks,
Takashi
