That explains better.  But NID 0x0b has no power control, so it
shouldn't be affected by itself.  Rather NID 0x04 power-down can be
the issue, at least, for speaker outputs.  For the headphone, both NID
0x09 and 0x03 are used.

Please try the driver without the patch, and get alsa-info.sh output
while testing from the speaker, and while testing the headphone,
individually.  Attach both outputs for comparison.  Maybe better to
compressed, otherwise it becomes too long.


thanks,

Please
