Hi everybody, I think there is something wrong with the intel-hda model autoprobing on my Acer TimelineX 4820TG.
The chip is recognized as: "hda_codec: ALC271X: BIOS auto-probing", but Pcwizard under Windows 7 reports it as Realtek ALC-269. Other info I found on the Internet seem to confirm 269 is the right codec. Can anybody confirm the correct model onboard the Acer 4820TG? Dmesg is populated with: hda-intel: spurious response 0x0:0x0, last cmd=0x270d80 [...] hda-intel: azx_get_response timeout, switching to polling mode: last cmd=0x00270e02 [...] hda_intel: azx_get_response timeout, switching to single_cmd mode: last cmd=0x00170503 azx_single_send_cmd: 177 callbacks suppressed I guess these erros result from wrong model autoprobing. Audio works anyway, but occasionally lags and shows major problems after enabling powersave features. I tried to force audio model with: options snd-hda-intel model=laptop-amic probe_mask=1, or options snd-hda-intel model=acer but it doesn't work. Is there a real problem in the codec model auto-probing? Should I file a kernel bug or am I missing something in the configuration?.
