Question about AT73C213.conf

[-- Attachment #1.1: Type: text/plain, Size: 707 bytes --]

Hello, 
 
 We are trying to get the audio chip (AT73C213) that comes on the AT91SAM9261-EK development board working. alsa-lib and alsa-utils, version 1.0.12 are currently installed. 
 
# aplay -l shows that the audio chip is recognized as a playback device (and has a driver).
 # aplay -L fails; there aren't any PCM devices configured.
 # alsaconf fails too. 
 
 We can't seem to find .conf files for any Atmel chips among the Alsa docs and files.  
 
 I assume the missing .conf file is the issue. Has anyone been successful with this? 
  
 Thanks, 
iyer

Basically it should work even without the dedicated card's *.conf file
as alsa-lib takes pcm/default.conf.  How did you install alsa-lib and
co?

Takashi,
 
 Thanks for your response..
 
 Here are the steps followed in installing the alsa-lib on an ARM board:  
 
 ALSA-lib install steps:
 
 [root@localhost alsa-lib-1.0.12]# CC=armv5l-linux-gcc ./configure --build=i386-linux --prefix=/board-rfs --host=armv5l-linux --target=armv5l-linux --enable-shared=yes --enable-static=no --disable-hwdep --disable-instr --with-headers=/board-rfs/usr/include/
 
 [root@localhost alsa-lib-1.0.12]# make TARGET_ARCH=arm 
 
 [root@localhost alsa-lib-1.0.12]# make install_root=/board-rfs prefix="/board-rfs" install
 
 Appreciate your input.

Is /board-rfs the correct path?  If you pass --prefix=/board-rfs, this
patch will be built into the binary, so the alsa-lib eventually
searchs for config files under /board-rfs/share/alsa/ and its sub
directories.

Thanks for your email, Takashi.
 
 The config files (ainit.conf, alsa.conf) are found in board-rfs/etc/alsa; not in /board-rfs/share/alsa/ and its sub directories. I'm not sure if this is the correct location for the config files. If not, do let me know.
 
 /dev/snd has the sound devices controlC0  pcmC0D0p  timer .
 
 On playing a soundtest executable (random sound generator):
  -bash-3.1# ./soundtest default
 ALSA lib pcm.c:2143:(snd_pcm_open_noupdate) Unknown PCM default
 cannot open audio device default (No such file or directory)
 
 Could this be tied in with the location of the config files ?
 
 Thanks in advance...

How did you install there?  Manually?
As default, configure script should choose $datadir/alsa as the config
location.

Also, don't pass --prefix=/board-rfs.  That's a wrong usage of prefix
option.

 Following up, the kernel was compiled using gcc 3.4 instead of gcc 4.1 and the alsa driver seems to work better. This is a toolchain problem, according to Atmel and our distribution vendor.
 
 But, we get the following error messages:
 
 -bash-3.1# aplay -D default Noise.wav
 Playing WAVE 'Noise.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Mono
 ALSA lib pcm_plug.c:773:(snd_pcm_plug_hw_refine_schange) Unable to find an usable access for 'default'
 aplay: set_params:909: Channels count non available
 
 Could it be possible that there is something fishy going on with the alsa-lib ?
 
 Appreciate your input..
 
 Thanks,
 iyer

But --prefix=XXX overrides the path embedded in the code.  For
installing to another root, passing DESTDIR=XXX at make install is the
standard procedure.

This is a different thing.  Now the system files are properly set and
alsa-lib reads them.  But, the driver  returns an error for the
required PCM setting.

Try to set $LIBASOUND_DEBUG to 1.  Then each hw_params error will be
displayed to stderr.  See alsa-lib/NOTES for details.

This is a different thing.  Now the system files are properly set and
alsa-lib reads them.  But, the driver returns an error for the
required PCM setting.

Try to set $LIBASOUND_DEBUG to 1.  Then each hw_params error will be
displayed to stderr.  See alsa-lib/NOTES for details.

But --prefix=XXX overrides the path embedded in the code.  For
installing to another root, passing DESTDIR=XXX at make install is the
standard procedure.
