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.
