Hi All,

I'm getting the following error when using an alsa application:

ALSA lib pcm.c:2099:(snd_pcm_open_noupdate) Unknown PCM default
Error opening PCM device default

This is an incomplete driver - it sounds like the userspace component is
missing.  Please provide a pointer to the source.

The output of the /proc files is:

# cat /proc/asound/cards
0 [siu-sh7343     ]: siu-sh7343 - Renesas sh7343 SIU
                    Renesas sh7343 SIU irq 108

What driver is this?  I don't see it in the ALSA tree.  There should be
a file /usr/share/alsa/cards/SIU-SH7343.conf that defines the default
PCM.

It is a new driver for the Renesas SH7343 Sound Interface Unit that I wrote. The product is a new cell phone with a LCD display that will play movie clips and audio to headphones. It worked well on my test board when I was using manually compiled alsa-lib and alsa-utils. Now I'm testing the software image that will be release to the customer and I get this errors. This image includes alsa libraries that were built by a different process (not sure about the differences though). Since the driver worked before, I think it might be a configuration problem... but I can't say for sure.

Thanks,


Carlos
