Not that I would see it as a real progress, but to clarify things: I 
have managed to solve this particular problem with capture by patching 
sound/arm/omap/omap-alsa.c (call omap_get_dma_dst_pos() instead of 
omap_get_dma_src_pos() from audio_get_dma_pos() in case of (stream_id == 
SNDRV_PCM_STREAM_CAPTURE)). The original code stopped working after 
changes introduced to omap_get_dma_src_pos() with this patch: 
http://marc.info/?l=linux-omap&m=121280267705523.

Unfortunatelly ;), sound/soc/omap/omap-pcm.c does it correctly without 
patching.
