[alsa-devel] soc underrun problem

[dfoley]

I'm currently having a problem with playing wave files

root at tsi-tpcxx:~# aplay /usr/share/sounds/alsa/Front_Center.wav
Playing WAVE '/usr/share/sounds/alsa/Front_Center.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Mono
mapped channel 10 to 2
underrun!!! (at least 130.662 ms long)
underrun!!! (at least 140.809 ms long)

I've narrowed it down to the commit ed3da3d9a0ef13c6fe1414ec73c9c1be12747b62 in linux-next/sound-2.6-tiwai.git.
   ALSA: Rewrite hw_ptr updaters

The audio works fine, when I reverse this commit.

My hardware is: CPU s3c2410 @ 202.8Mhz codecs (ak4550 or tlv320)

Anyone else seeing this ?
