Comment (by anonymous):
There's more than one bug being reported here.
The "losing sound after changing channel" bug definitely lies in the
cx88-alsa driver, and it affects sound output through ALSA when changing
channels with tvtime as well. This can be fixed by removing the
cx88_stop_audio_dma/cx88_start_audio_dma in set_audio_finish in
cx88-tvaudio.c.
The issue of switching from digital to analog displaying snow isn't
exactly a bug, it's a feature, which can be turned off by adding a file in
/etc/modprobe.d containing "options dvb_core dvb_shutdown_timeout=0".
The original "no sound on initial tuning" bug is one I haven't seen
(because I don't use the analog audio out), but I would guess it's also a
driver bug; it sounds like the multiplexer isn't being set properly when
changing from digital to analog. MythTV doesn't have direct control of
that process, which is why I think it's probably not a MythTV bug.
