'Splain please re: mixer, alsa, pulseaudio and tvtime??


My problem is not yet with tvtime but my question trail starts there.

tvtime has been upgraded to use alsa for sound rather than OSS.  To do
that I need to re-set  <option name="MixerDevice" value="default/Line"/>
to something like mixer="DEVICE[:CH]" e.g hw:0/CD; where DEVICE = hw:0
and [:CH] = /CD.

ls /dev/mixer no longer exists.  Where does tvtime find DEVICE and where
do I find DEVICE?  How do I know it is the new name of the mixer?

Which channel [:CH] do I use?  Is it from the same list as tvtime.xml
suggests for OSS or is it a different list?  Given that I have an
internal sound card on a PCIe bus how would I go about deducing which
channels to try first?

Now that I have the latest kernel and tvtime upgrade, these questions
are so that I can overcome the confusion of many, many hours of
experimentation and reading of outdated google comments. Hopefully, if I
can solve tvtime or at least be looking at the correct configuration I
can go on to solve problems with RhythmBox and others.

A bit of a rant:  The biggest problem that I have, and that others have
mentioned they have, is the lack of trustworthy documentation --
something that starts with the real basics, on how alsa, pulseaudio, and
the various guis work.
