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.
I forgot to mention that I hear noise if I cat a file to /dev/dsp or
/dev/audio. Not sure it this means anything.
Thanks,
Carlos
