Hi, I'm trying to work out how to record from an S/PDIF input using a Terratec 7.1 Space (Envy24 based card, supported by ICE1724 Alsa driver). I simply can't work it out. Under Windows it's necessary to use the Terratec control panel to select S/PDIF as the recording source (rather than the analogue mixer/sources). What I think I should do under Linux is something like:
There is a workaround in the alsa-lib tree now for this issue <http://hg-mirror.alsa-project.org/alsa-lib?cmd=changeset;node=76c855e68dd8;style=gitweb>

OK, the problem is the confliction of "IEC958 Playback Route" and "IEC958 Capture Switch". We need to fix either mixer layer or rename it, e.g. from "Playback Route" to "Playback Source". The patch below (for alsa-lib) is a temporary workaround to add the automatic toggle of "IEC958 Capture Switch" over iec958 (spdif) PCM. This makes the spdif recording working even without the fix suggested in the above.
(The fix mentioned was to, as root, run "alsactl store" to save the current mixer settings in /etc/asound.state, manually edit the "IEC958 Capture Switch" entry to true, and then run "alsactl restore") So you can either apply this fix manually or the patch to (IIRC) /etc/alsa/cards. -- imalone
