Hello guys. I am writing to you all to talk you about a strange behaviour of the Intel HDA Audio device on an EEE PC 1101H. The audio device at some point simply doesn't react to commands, giving in dmesgo utput like this:
[22321.638079] snd_hda_intel 0000:00:1b.0: azx_get_response timeout, switching to polling mode: last cmd=0x00170503 [22322.641410] snd_hda_intel 0000:00:1b.0: azx_get_response timeout, switching to single_cmd mode: last cmd=0x00170503
This looks already bad. It means that power down of the codec failed.
But, the recent version should ignore this error. There was a logic failure to check this, but this was corrected recently.
Could you check the latest 4.0-rc whether it works better? If not, take alsa-info.sh output snapshots at good and bad working moments. Run the script with --no-upload option, and attach the outputs (better compressed).
