Great! The patch is perfect!

Only 1 problem found, what should be fixed:
the sh_audio->o_bps field must be filled with output bitrate (bytes/sec).
it's normally done by dec_audio.c simply multiplying bits_per_sample,
channels and samplerate, but it isn't ok for hardware decompression.
and as this value is used for A-V sync, you get probelms with bad value!

i think something like this should be ok:
sh_audio->o_bps=sh_audio->i_bps+(ac3_frames_per_sec*extra_header_bytes)

if still not work, then there is a possible problem of audio card's timing.
i mean the sblive retuns bad value for buffer pointer :(

i'll commit this patch to cvs now.
