Hi!
I'm trying to record through the RCA S/PDIF IN port. My system is:
Linux 2.4.19 i386 SMP + Alsa 9.0rc1 CMIPCI driver
The playback works fine but recording looks like this:
joshua@remix:~$ arecord -v -D spdif -t wav -f S16_LE -r 44100 -c 2 iectest
Recording WAVE 'iectest' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo
Hooks PCM
Its setup is:
stream : CAPTURE

format : S16_LE
subformat : STD
channels : 2
rate : 44100
exact rate : 44100 (44100/1)

When i disconnect the cable then i get an I/O error so it is
*somewhat* connected. However, i can't get a normal recording.
Does the driver from C-Media work better than the Alsa driver?
I haven't tried it yet (20% done downloading ...).
Any other suggestions? My asound.state is attached.
