[SOLVED] Xonar ST - There is no sound output from s/pdif

[agent_kith]

I'm using the Xonar ST card.After the start of the OS there is no sound at the output from s/pdif.It is necessary to run the alsamxer and manually disable the option "s/pdif loopback". This option is also turned on when you press "Music Player"-"Set Volume to 100%". Is it possible to disable the option "s/pdif loopback"  when the OS starts?

Hmm. Not sure that can be done in general, although it should be pretty easy to do this just for the Xonar ST (or STX).

Only have the STX kept in storage somewhere (All ST are sold out in my area) so hopefully the same controls will work for the ST.

Will let you know if I get this done. After you have manually adjusted the volumes in alsamixer, does the settings get lost on reboot? I havn't checked this myself (as my audio device has no settable controls), so wasn't aware settings aren't saved by default.
