These patches apply cleanly to 'v2.6.37' 3c0eee3fe6a3a1c745379547c7e7c904aa64f6d5
of git://git.kernel.org/pub/scm/linux/kernel/git/khilman/linux-davinci.git.
The kernel was built with the 'da8xx_omapl_defconfig' from the omap-l1tree, and 'make menuconfig' to enable ASoC (the defconfig already has CONFIG_REGULATOR=y, CONFIG_REGULATOR_DUMMY=y, and CONFIG_REGULATOR_TPS6507X=y).
Testing was done on a da850evm by tftp'ing the kernel into ram, and using the SPI-flash-based rootfs from the PSP that shipped with the board.
Using 'arecord -r 48000 -c 2 -f S32_BE -t raw -v -d 1 > /tmp/arecord.cap' produced a file of 384000 bytes (48000 x 2 x 4 bytes/sample). 'arecord -r 48000 -c 2 -f S32_BE -t raw -v > /dev/null' ran flawlessly for several hours.
I was not able to reproduce Sudhakar's problems with 'arecord -f dat | aplay -f dat'.
Did you try the above, immediately after the da850evm boots? I am not facing the issue if I run arecod and aplay together after executing arecord or aplay individually.
Thanks, Sudhakar
