Oh, ok. I seem to remember a "software"/"hardware" choice - ah,
if you do a "lavplay -h" you'll see:
-p/--playback [SHC] playback: (S)oftware, (H)ardware (screen) or
(C)ard
what happens if you use "-p S" in the lavplay command?

One good thing is that now you have the latest SDL :)
I think "-p S" will work for you though.

Hurrah! That is good, and says SDL is working.

I made a mistake - that should, of course, have been "-o test.mp2".
The output of mp2enc is a MPEG-1/Layer-2 file not a WAV file.

Try
mpg123 test.wav
or if you use "-o test.mp2" (as I should have written)
mpg123 test.mp2
that will work I believe.

mp2enc -h
-r num Force output sampling rate to be num Hz (default: 44100)
22050 is not a valid rate for VCD/DVD/SVCD - mp2enc is upsamping the
audio to 44100. You can specify a different rate with "-r".
