ALSA with OSK

ALSA with OSK

[Dirk Behme]

Hi,

just tried ALSA on OSK with recent 2.6.16:

# madplay /mnt/nfs/foo.mp3
MPEG Audio Decoder 0.15.2 (beta) - Copyright (C) 2000-2004 
Robert Leslie e.
           Title: Foo
          Artist: Foo
           Album: Various - New Project
           Track: 1
           Genre: Blues
output: ioctl(SNDCTL_DSP_SYNC): Invalid argument
#

Any quick idea?

Many thanks

Dirk

How about if you try to play wav with aplay? Or by applying 3 alsa
patches send to list 2 weeks ago?

Thanks! Does aplay play mp3? I applied the patches, but no 
difference:

Any other working mp3 player?

Best regards

BTW: Any plans to apply the pending patches?

Hello,

 During the OSS days, I think I had similar error on certain 
sampling rate, while other rates were just OK.  

 It might be interesting to try other sampling rates if you 
have the MP3 encoder handy.

 Ishigami

aplay doesn't support mp3 files. You can try this command instead:

madplay -q -o raw:- file.mp3 | aplay -q -f cd

It uses madplay just for mp3 decoding and aplay to actually "talk" with alsa.
