Thanks, I didn't know about the 'sndfile' option.
This works perfectly for OGG-files (and for WAV and FLAC as before).

I just have to change one line in my original example:

ai-add sndfile,house_lo.mp3

libsndfile doesn't support MP3, so those still don't work.

But anyway, I can live with WAV/FLAC/OGG.

As this uses libsndfile, it doesn't work for MP3s either.

Yes, thank you!

@Willem:
Thanks for the hint about the 'file' command.
This might work, but I prefer if everything can be done with ecasound.
I'm glad that OGG works now, and I can live without MP3 support.

cheers,
Matthias
