The interrupt handler always provide runtime->period_size data, so it works correctly only if buffer_size was a multiple of period_size. This patch fixes periodic click noise. Signed-off-by:

snd_pcm_lib_preallocate_free_for_all() is called from snd_pcm_free() just after calling the private_free routine. So there should be no need to call it in driver's private_free routine. Signed-off-by:

This header file exists only for some hacks to adapt alsa-driver tree. It's useless for building in the kernel. Let's move a few lines in it to sound/core.h and remove it. With this patch, sound/driver.h isn't removed but has just a single compile warning to include it. This should be really killed in future. Signed-off-by:

This patch fixes the locking bug in the at73c213 SPI sound driver. This bug was triggered because spinlocks were wrapped around the spi_sync call which might sleep. The fix was to add a mutex to the sound driver and replace the spinlocks in the mixer functions with mutex lock/unlock. Tested on STK1000/STK1002. Signed-off-by:

This patch adds support for the AT73C213 DAC using the misc Atmel SSC driver in I2S mode. The driver also requires a SPI to setup the registers and control volume. It has been tested with an AT32AP7000 on the ATSTK1000 development board. The driver should also work with any Atmel device with an SSC module supported by the Atmel SSC driver (atmel-ssc). The atmel-ssc driver is just submitted to the Linux kernel. Please see mail thread http://lkml.org/lkml/2007/7/16/32 Signed-off-by:
