[Alsa-user] USB Audio & iecset

[Peter v. R. <the...@ya...>]

Hi, 

I'm trying to route audio to my USB Audio device's
SPDIF output using mplayer. 

My .asoundrc looks like this:

pcm.usb44 {
        type plug
        slave {
                pcm "hw:1,0"
                rate 48000
        }
}

aplay -D usb44 works fine. How mplayer -ac hwac3 -ao
alsa1x:usb44 complains:

AF_pre: 48000Hz 2ch AC3
alsa-init: requested format: 48000 Hz, 2 channels, AC3
alsa-init: soundcard set to
iec958:AES0=0x2,AES1=0x82,AES2=0x0,AES3=0x2
ALSA lib setup.c:548:(add_elem) Cannot obtain info for
CTL elem (MIXER,'IEC958 Playback AC97-SPSA',0,0,0): No
such file or directory
alsa-init: playback open error: No such file or
directory
Could not open/initialize audio device -> no sound.
Audio: no sound
Starting playback...

[root@localhost /]# iecset -c1
control "IEC958 Playback Default" not found


I'm using:

MPlayer 1.0pre4-3.3.2
Alsa 1.05a (atrpms.net) 

Any ideas/comments/suggestion most welcome!

Thanks,
Peter
