I need help with the sound on our appliance. We are
compiling the kernel (2.6.32.4) with the alsa and the drivers configured as
built -in.
when the kernel is starting it loads the driver
(Intel HDA) and recognizes the sound card successfully (VIA
VT82xx).
All the relevant devices appear (under /dev and
under /proc). I can see IRQ 17 assigned to the sound.
However when trying to play a sound I get an
Invalid Argument error.
It seems that the ioctl commands on the device
return EINVAL.
The dmesg command shows the following
messages:
ALSA sound/core/oss/pcm_oss.c:871: No usable
accesses
ALSA sound/core/oss/pcm_oss.c:871: No usable accesses ALSA sound/pci/hda/hda_codec.c:1096: hda_codec_cleanup_stream: NID=0x10 ALSA sound/pci/hda/hda_codec.c:1096: hda_codec_cleanup_stream: NID=0x11 ALSA sound/pci/hda/hda_codec.c:1096: hda_codec_cleanup_stream: NID=0x12 ALSA sound/pci/hda/hda_codec.c:1096: hda_codec_cleanup_stream: NID=0x13 Does anybody have any idea what can be the
problem?
Thanks
