[MPlayer-users] Problem using MPlayer and ALSA

[Pierre CLARENC]

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"
00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High Definition
Audio Controller (rev 02)

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

Do you have any idea to fix this problem?

Thanks in advance,
