The actual debug channel for that file seems to be dsalsa. I'll try to get a
log. I did notice a suspicious detail when messing with debug outputs. During
normal operation, "writepos" appears to always be in front of "playpos", which
makes sense as buffer should be filled in front of play position. E.g.:

err:dsalsa:IDsDriverBufferImpl_GetPosition hw_pptr=0x000002f0,
hw_wptr=0x00001510 playpos=3008, writepos=21568
err:dsalsa:IDsDriverBufferImpl_GetPosition hw_pptr=0x000004cf,
hw_wptr=0x000016f0 playpos=4924, writepos=23488
err:dsalsa:IDsDriverBufferImpl_GetPosition hw_pptr=0x000006af,
hw_wptr=0x000018cf playpos=6844, writepos=25404

But after the sound disappears, writepos is trailing playpos, e.g.:

err:dsalsa:IDsDriverBufferImpl_GetPosition hw_pptr=0x0000031f,
hw_wptr=0x00000140 playpos=3196, writepos=1280
err:dsalsa:IDsDriverBufferImpl_GetPosition hw_pptr=0x000004ff,
hw_wptr=0x0000031f playpos=5116, writepos=3196
err:dsalsa:IDsDriverBufferImpl_GetPosition hw_pptr=0x000006df,
hw_wptr=0x000004ff playpos=7036, writepos=5116

Maybe that's the problem.
