it gave me a starting point for the audio but it didn't do much. Here is
what happened:
First I had to figure out which method my system used so :
bmike1@c521 ~ $ sudo dpkg-reconfigure alsa
bmike1@c521 ~ $ sudo dpkg-reconfigure pulse
bmike1@c521 ~ $ sudo dpkg-reconfigure jack
bmike1@c521 ~ $ sudo dpkg-reconfigure jackd
all of which gave me a similar error
dpkg-query: package 'jackd' is not installed and no information is available
Use dpkg --info (= dpkg-deb --info) to examine archive files,
and dpkg --contents (= dpkg-deb --contents) to list their contents.
/usr/sbin/dpkg-reconfigure: jackd is not installed
finally I happened upon:
bmike1@c521 ~ $ sudo dpkg-reconfigure pulseaudio
Processing triggers for libc-bin (2.19-0ubuntu6.6) ...
But that didn't help any. So I suppose I'll look at the man page and see if
any of the options help:
bmike1@c521 ~ $ man dpkg-reconfigure
bmike1@c521 ~ $ sudo dpkg-reconfigure --default-priority pulseaudio
Processing triggers for libc-bin (2.19-0ubuntu6.6) ...
bmike1@c521 ~ $ sudo dpkg-reconfigure --force pulseaudio
Processing triggers for libc-bin (2.19-0ubuntu6.6) ...
Nope. Looking at the man pages it seems as if you are supposed to be
presented with configuration questions. Hmmmmmm..... I got none of that.
