Hi all,

After my issues last week I've rolled right back to mythbuntu 12.04.
Everything is almost back to normal but I still have some wierd audio
issue.

mythtv is actually working fine (audio works), but audio from any
other application is not (vlc, plex etc). I can only assume the
problem relates to the "default" audio setting.

I have a Zotac ION series 1

This is my /etc/asound.conf

pcm.hdmi-remap {
       type route
       slave.pcm hdmi
       ttable.0.0 1
       ttable.1.1 1
       ttable.2.4 1
       ttable.3.5 1
       ttable.4.2 1
       ttable.5.3 1
       ttable.6.6 1
       ttable.7.7 1
}

pcm.!default {
type plug
slave.pcm hdmi-remap
}

If I use speaker-test -c6 I get no sound and no error...

phil at echo:~$ speaker-test -c6

speaker-test 1.0.2

phil at echo:~$ ^C

However if I run as root, I hear sound from each speaker the way I'm
expecting. It would not appear to be a permission issue as mythtv can
send audio correctly as the user that is failing (albeit by specifying
a device rather than default).

There is no .asoundrc file for the user although I have tried copying
/etc/asound.conf to ~/.asoundrc with no change to the fault.

Any suggestions as to what I might be doing wrong?

Phil
