[alsa-devel] hda_intel messages showing up in dmesg

[Andrew Paprocki]

I'm seeing these messages show up in dmesg every once in a while. If
anyone has ideas as to why I'd be seeing these, I can help track down
any potential problems. I am having problems where ALSA playback
stutters while using the OSS-compatibility layer for ALSA works fine
with no stuttering.

After inserting the module w/ model=6stack-dig:

ACPI: PCI Interrupt 0000:00:14.2[A] -> GSI 16 (level, low) -> IRQ 16
hda_intel: azx_get_response timeout, switching to polling mode: last
cmd=0x225f0d00
hda_intel: azx_get_response timeout, switching to single_cmd mode:
last cmd=0x225f0d00
ACPI: PCI Interrupt 0000:01:05.2[B] -> GSI 19 (level, low) -> IRQ 18
hda-intel: Invalid position buffer, using LPIB read method instead.

After inserting the module w/ no model defined:

ACPI: PCI Interrupt 0000:00:14.2[A] -> GSI 16 (level, low) -> IRQ 16
hda_codec: Unknown model for ALC883, trying auto-probe from BIOS...
ACPI: PCI Interrupt 0000:01:05.2[B] -> GSI 19 (level, low) -> IRQ 18
hda-intel: Invalid position buffer, using LPIB read method instead.

I've only seen the azx_get_response messages print out once. I see the
LPIB message print out every once in a while.

Thanks,
