When booting a LiveCD (CentOS 5.4 with alsa 1.0.17
kernel 2.6.18.el5) speaker-test works fine. However when we use
custom built kernel version 2.6.32.4 with alsa version 1.0.17 or
1.0.23 on the same hardware the speaker-test fails with the
following error:
ALSA lib pcm_direct.c:866:(snd1_pcm_direct_initialize_slave)
snd_pcm_hw_params_any failed
ALSA lib pcm_dmix.c:1020:(snd_pcm_dmix_open) unable to initialize
slave
After modifying the pcm/pcm_params.c to enable REFINE_DEBUG and
also added printout of the driver version(pcm_hw->version) to
the hw_refine_call function. We got the following output:
REFINE called:

In this output we noticed that the hw_refine is returning 22
(Invalid Argument) and some of the returned parameters seems to be
unusual such as the PERIOD_BYTES: [128 536870912]. Can this be the
cause of the problem?
Anyone have any ideas why this problem happens? Or what else we
should investigate?
