Hi,

I have a AMD 785G motherboard where there is a worrying situation logged by ALSA drivers. Sound nevertheless works.

lspci: 00:14.2 Audio device: ATI Technologies Inc SBx00 Azalia (Intel HDA)

dmesg: HDA Intel 0000:01:05.1: PCI INT B disabled HDA Intel 0000:00:14.2: PCI INT A disabled HDA Intel 0000:00:14.2: PCI INT A -> GSI 16 (level, low) -> IRQ 16 HDA Intel 0000:01:05.1: PCI INT B -> GSI 19 (level, low) -> IRQ 19 HDA Intel 0000:01:05.1: irq 28 for MSI/MSI-X HDA Intel 0000:01:05.1: setting latency timer to 64 hda-intel: azx_get_response timeout, switching to polling mode: last cmd=0x000f0000

I tried position_fix=0, 1 and 2 with no difference. I also tried enable_msi=0 to make it use IO-APIC interrupt. Then this error is not displayed, sound works, but again no interrupts are generated at least count is not growing in /proc/interrupts.

Please tell me what else I can try and what debugging info you need.

The switching to polling mode itself isn't a big problem at all. This can be usually ignored. If you have any other issues wrt sound quality, just ignore this.

Hi,

Yes sounds quality seems OK. So there are no performance issues with polling?

It might be, but usually negligible.

Messages as this usually raise attention so if it is normal I suggest changing the message to something less alarming.

It's certainly a thing that should raise attention. It means that something is actually wrong. But, not that too wrong to fix urgently.
