I have installed mandriva 2010 on virtual box
when using xmms and libao output plugin to play system sound startup3.wav
xmms hang at the end of the playback only when enable buffering in libao output plugin.(configure output plugin in xmms, unfortunately default is enable buffering buffer size 3000 chunk size 1000) ,
xmms does not hang when you disable the buffer or using liboss/libALSA output plugin
The last message in the pulseaudio server is D: protocol-native.c 'underrun on libao[xmms] playback stream' , 0 bytes
in
queue.
The sound card seem running since hw_ptr and appl_ptr are increasing when cat /proc/asound/card0/pcm0p/sub0/status
After a while , the following message appear
E:alsa-sink.c : ALSA woke us up to write new data , but there was
actually
nothing to write!
The above is exactly what I see periodically Raymond, so, what, if any, is the fix?

Do you mean that you cannot reproduce the xmms hang bug on your ens1371 or via8237 ?
xmms always hang/freeze at 4 second as xmms display the total length of startup3.wav is 5 seconds
you have to ask mandriva 's maintainer why enable buffering is the default option since xmms did not hang when I disable buffering in libao plugin
For fefora 10 and 13 , they only provide liboss, libALSA and libpulse plugin for xmms I have no idea about the chunk size in libao plugin
