Hello pablo,

for gnome radio it's maybe a solution. But even then it's to processor intensif. For tv card itself it's a pain in the ass since there is a delay between image and sound. Off course i do not route out the sound to /dev/dsp in tv time. the only control we used was the /dev/mixer emu to untoggle the specified alsa mixer channel and change volume. My tv time card is connected to CD in from motherboard. Some connect it to line in by absence from other inputs. Then we don't have delay between image and sound and are not using (spoiling) valuable processor time. Sound can also be untoggled using alsa mixer. Or even better gnome-alsamixer.

Another option off course is the use of loopback into pulse, But since pulse does not support my sound card how it should be and there is no way to solve that. I do it straight trough alsa. On top of it you can't mixed several loopback inputs togheter with pulse Yes Pulse is very very far from complete.

Note: most new software use direct input into alsa . Tvtime and gnome radio are not under developpemnt anymore. For tv time there is a patch made to use direct hw:0:Line or CD instead of passing trough /dev/mixer . But I still did not found this patched version compiled for amd64 or the latest modified source to compile this myself. It seems to be called tvtime version 1.0.2-8sr... in ubuntu there is still version 1.0.2-6.
