           Summary: azx_get_response timeout; ALC262 codec unknown
           Product: Drivers
           Version: 2.5
     KernelVersion: 2.6.26.2
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Sound(ALSA)
        AssignedTo: perex at perex.cz
        ReportedBy: peter.ganzhorn at googlemail.com


I'm getting the same messages in dmesg for every 2.6 kernel, and it seems to be
unnoticed until the most recent kernels:

[...]
Advanced Linux Sound Architecture Driver Version 1.0.16.
HDA Intel 0000:00:1b.0: enabling device (0000 -> 0002)
ACPI: PCI Interrupt 0000:00:1b.0[A] -> GSI 22 (level, low) -> IRQ 22
PCI: Setting latency timer of device 0000:00:1b.0 to 64
hda_codec: Unknown model for ALC262, trying auto-probe from BIOS...
hda_intel: azx_get_response timeout, switching to polling mode: last
cmd=0x019f000c
ALSA device list:
  #0: HDA Intel at 0x88200000 irq 22
[...]

Sometimes the line
"hda_intel: azx_get_response timeout, switching to polling mode: last
cmd=0x019f000c" does not show up at boot time, but it will show up within one
or two hours randomly, i.e. it shows up while the sound card is active or
inactive. I can not see any trigger for this.

Sound keeps working despite the error, but I'm experiencing random
"sound-lockups", especially when using wine.
The sound seems to work just fine, but sometimes when the app does not play any
sound it might happen the next time it is supposed to play sound it won't.
Until killing the app that caused it all other apps trying to play sound will
"freeze".
This mostly happens with PokerStars run with wine. I'm running mpd, which won't
play music until re-starting wine after this happend.

I suspect all of this (the sound errors and the dmesg messages) are connected,
but that's just a guess.
Please investigate this!

I'm running Debian Lenny with a self-compiled 2.6.26.2 kernel, the system's
packages are up2date.

PS: Thanks for your great work!
