Sox did what it was told to do. The problem is that mpeg_musicin is a
finicky consumer of aiff files. I change the intermediate format to
WAV and it works fine:
The following patch applied to /usr/X11R6/lib/X11/fxtv/fxtv_cnvt.sh
fixes it:
# Do we need an intermediate file?
if [ $mpeg_enc = YES ]; then
- out_soxfn="$out_fnbase.aiff"
- out_soxfmt="AIFF"
+ out_soxfn="$out_fnbase.wav"
+ out_soxfmt="WAV"
else
out_soxfn="$GAout_fn"
out_soxfmt="$out_fmt"

Well, that's not why it's failing for me. I'm not using the SB AWE32;
I can record 16-bit, 44,100 Khz stereo, and get the same results.
While I'm at it - has anyone managed to use the new pcm drivers to do
serious audio work? Or should I give up and use Windows for this?
Thanx,
