Debian + Audio

[Cure]

Has anyone gotten the audio output to work with Debian?  If so what program did you use for testing, did you have to install drivers, etc?

Thanks,
Rob

I have audio working with mplayer and video files... I haven't change kernel configuration, so I think audio is supported.

Mmmhhh... Maybe here is the answer, sorry:

Code Select Expand


Opening audio decoder: [ffmpeg] FFmpeg/libavcodec audio decoders
AUDIO: 48000 Hz, 2 ch, s16le, 70.0 kbit/4.56% (ratio: 8749->192000)
Selected audio codec: [ffaac] afm: ffmpeg (FFmpeg AAC (MPEG-2/MPEG-4 Audio))


mplayer uses libavcodec from ffmpeg to decode audio. So I think you can try with that.

Thank you Lorenzo.  Up until now I was trying with earphones.  The next step will be to try mplayer and if that doesn't work I will also try with powered speakers.

I have built my own kernel so I'll post a followup if I get it working.

I tested this a while back but forgot to reply.  I did manage to get audio working on my A13 and don't see why it wouldn't work on the iMX233 as well.  I used http://linux.die.net/man/1/speaker-test:
speaker-test -t sine -f 300

It also runs .wav files, but you must first convert them to a 1 channel .wav and put the correct -r Hz value:
speaker-test -t wav -c0 -s1 -r 44100 -w /mnt/ftp/ringtone.wav

I want to play some music with my olimex board (A13) and if I run speaker-test the sound works, but mpg123 doesn't work is there anything special I have to consider?

Ok now I can play sound with alsaplayer, but how can I find out which device I have to use for mpg123?
