I have to revert the commit on asound.conf it make mic not working:

Ah, yes - I only did the playback part because I don't really use the
mic myself, so didn't think to test that.
I've modified the config a bit so recording also works - in fact, I can
now both playback and record multiple times simultaneously. :)
(I played around with this a bit, as I found that with the right volume
settings, arecord|aplay keeps about the same volume for some things, so
then I could use another window to record and replay parts of it. :) )
found without the asound.conf the software volume control still works fine.
Hm, sort of - for me, the control still shows up in alsamixer (probably
due to it having state in ALSA, since it's still there after a reboot
unless I remove the .state file), but it isn't actually used by newly
started programs - their volume is not affected by it. At least for me.
Another thing I found while testing the above, is that after I run aplay
(playing a file recorded with arecord), nano (the editor) stops working
- when started, it immediately exits after printing the message
"Received SIGHUP or SIGTERM".
It starts working again if I log out and then back in (this is via ssh),
or if I run bash and then exit it, so it's easily worked around - but
still odd.
I'm still on the same OS image as last time, though (haven't gotten
around to upgrading yet, should do that soon), so for all I know this
might have been fixed already...

P.S. As you might have understood from the above, I tend to use the
"nano" editor - so keeping my notes on this thing is a bit punny, since
I then run "nano notes" on my NanoNote. ;)
