[mythtv-users] Mythmusic no longer working on remote FE

Hi all,

I have a problem with mythmusic that only popped up about a month ago,
and in the absence of any error message I have no clue how to solve it.

My system is a dedicated mythbuntu BE with everything in storage groups,
accessed by a remote mythbuntu FE. The FE has HDMI towards my TV and
S/PDIF (optical) towards my amp. In my general setup I have the HDMI
(ALSA:hdmi:CARD=NVidia, DEV=0) output defined, and in mythmusic setup I
use the optical output (ALSA:iec958:CARD=Nvidia,DEV=0, as taken from the
detect audio in the general setup). This has worked flawlessly for about
a year.

I don't tinker with a setup that works, and the only changes have been
mythbuntu and myth-fixes updates. Currently I am running mythbuntu 10.04
with fixes/0.24 v0.24.1-112-g40f3bae

A couple of weeks ago I wanted to play some music again, and mythmusic
didn't make a sound anymore. It still finds all my music and playlists,
but when I select something to play it just stops. Normally on the
screen, next to the artwork, you see the song title, the group, and the
album with underneath the time vs total time and a progress bar. The
time and bar no longer show, and sometimes the artwork doesn't show up
either (just a black square, didn't happen before). When I exit
mythmusic it doesn't give me the "exit while continue to play" question.

Thinking that there was something with the optical output I changed
music settings to "default" audio, which should point to the setting in
general settings (i.e. hdmi). Same problem.

Meanwhile the sound via hdmi for recordings and videos is just fine.

The log file does not show me anything obvious:

Does anyone have an idea of things I can try to get mythmusic functional
again?


Thx, and have a great 2012!
