I'm unable to record from a toslink source as described below, it's
possible I've just missed some detail.
Fedora Core 5
Kernel: 2.6.16-1.2122_FC5
Alsa: alsa-lib-1.0.11-4.rc2
details follow:
Summary:
Recording from SPDIF input on ICE1724 device (Terratec 7.1
Space, but same chipset as the 5.1 Sky) records only silence.
Rebooting the same machine into windows recording works fine.
Recording source is a DAB radio, apparently at 32kHz (at least,
arecord tells me it was unable to select the requested rate
if I choose anything else).
$ arecord -D hwplug:0,1 -f cd test.wav
The equivalent hw:0,0 (analogue) successfully records from
line-in with a loopback cable.
I have checked alsamixer, and the IEC958 source has capture
enabled, as does line-in. The alsa matrix claims tosio for
the 5.1, does that work?
Is "Optical" chosen for "IEC958 Capture Source"?
Better to show the mixer status (e.g. /etc/asound.state) for further
diagnosis.
Well, this is /etc/asound.state, whether it corresponds to what
I'm actually using I don't know.
Optical is selected for the IEC958 capture source, I also tried
CD just to see if it made a difference.
Thanks for your time.
