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.
Please try the patch, and once turn off "IEC958 Capture Switch"
manually (via alsactl store and restore), then record via "spdif" PCM,
such as
% arecord -Dplug:spdif -fdat foo.wav
If it's confirmed to work, I'll commit to HG repo.
Thanks,
Takashi
