Hi, I’m trying to get an FM801 to work on FC3. It didn't work on FC1 in this
system and I was hoping that an upgrade to FC3 would get it going. I have
seen a web page about the FM801 but I’m stuck getting it to make any sound.

So I guess that means the system has found the hardware and the drivers are
I have unmuted and maxed out all the faders in alsamixer. I can hear a
slight tick in the output when I mute and unmute the mic channel and some of
the other channels so there is some sign of life. 
But I cant get the thing to play any sound files.
aplay bigfile.wav results in silence. The Gnome sound tester does not play a
sound file. Audacity crashes on playing a file. So something is not right. I
noticed some *oss modules loaded is that good or bad?
Is there something I need to do to tell applications to direct their sound
to this device???
A direct copy of a wav file to /dev/dsp, which I think should make a noise,
doesn’t. Or is there another way to copy data directly to the device as a
I know sound works in Linux because I have another system with an SBLive
that works. (Sorry that just reflects my frustration with getting this
working) So what have I missed???? Does any one here have an FM801 based
card working with FC3 who can offer me some guidance

Any help most welcome..
