Did you save it as a raw file?  Otherwise gmail interface breaks lines
and spaces badly.

Then pass like "pasuspender -- arecord ....".  Depending on PA
version, you need "--".

You have the following kernel messages:
[ 3798.888009] ALSA hda_intel.c:717: azx_get_response timeout, switching to polling mode: last cmd=0x001f000a
[ 3799.892016] ALSA hda_intel.c:756: hda_intel: azx_get_response timeout, switching to single_cmd mode: last cmd=0x001f000a

This is rather a fatal error, which makes impossible to get
unsolicited events from the codec.

And, judging from alsa-info.sh output, you are still using the old
driver.  With the new driver, you must have "Auto-Mute" enum mixer
element.  That is, the installation from the snapshot tarball failed
somehow.  Double-check what went wrong.  The error above should have
been fixed in the recent version.

BTW, I fixed another issue in auto-mute mode, so try the latest
snapshot tarball again.


thanks,
