Important or not, I have to fine down my provious reports on what works
and what does not:
- original patch applied with other ams-delta related patches
on linux-omap-2.6.16, as it was designed for:
- playback: works, with both aplay and >/dev/dsp,
- capture: works with </dev/dsp, gives null output with arecord
- original patch ported to the last l-o commit supporting omap-alsa:
- playback: works as before,
- capture: both </dev/dsp and arecord give null output,
but DMA interrupts still work.
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.
