Interesting. I will give this a shot. Though I note that doing the above
stuff to pulseaudio would still require a user's intervention to change
everything in Preferences->Sound to Alsa. I find this uncomfortable in
the sense that Ubuntu is supposed to be user friendly. Just choosing
"Default" should work when pulseaudio is deactivated. Again, all these
kludges just make Ubuntu the same as Debian. Debian is my default OS but
I always push Ubuntu for novice users who want to try Linux trumpeting
its easy of use.
BTW, when pulse audio is running, is alsamixer (the console level
controls) supposed to work? In a laptop running Intrepid, it works, but
on a computer running Hardy it doesn't. On the hardy machine, I get
something like this:
*** PULSEAUDIO: Unable to connect: Connection refused
alsamixer: function snd_ctl_open failed for default: Connection refused
So how does alsamixer related to pulseaudio?
