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.
thanks,
Takashi
