Hi,
I have problems using Mplayer (MPlayer SVN-r30100-snapshot-4.4.1) with ALSA.
I want to play a RTP stream accessed through RTSP. When I use Ethernet
interface, audio playback works well but when I use Wifi, audio playback
works most of the time but sometimes I have the following message :
[AO_ALSA] Write error: Broken pipe Audio :
100.1%
[AO_ALSA] Trying to reset soundcard.
mplayer does not crash but plays silence during about one second.
For information, I decode MP3 file using ffmp3 codec :
Forced audio codec: ffmp3
Opening audio decoder: [ffmpeg] FFmpeg/libavcodec audio decoders
AUDIO: 48000 Hz, 2 ch, s16le, 256.0 kbit/16.67% (ratio: 32000->192000)
Selected audio codec: [ffmp3] afm: ffmpeg (FFmpeg MPEG layer-3 audio)
When I try with OSS, sound works well.
Some commands results may help you :
lspci | grep "Audio"

cat /proc/asound/card0/codec#0 | grep Codec
