Hello All;

I feel confused by the presence of 2 different copies of ac97_codec.c:

   jutz-gnto ~ # find . -name ac97_codec.c
     ./alsa-driver/pci/ac97/ac97_codec.c
     ./alsa-kmirror/pci/ac97/ac97_codec.c

worse yet,they are not in sync:

jutz-gnto ~ # diff -w ./alsa-driver/pci/ac97/ac97_codec.c  
./alsa-kmirror/pci/ac97/ac97_codec.c
1d0
< #include "adriver.h"

< #else /* <= 2.6.0 */
< #define snd_ac97_dev_register NULL
< #define snd_ac97_dev_disconnect       NULL
< #endif


Which of these am i supposed to use? am i supposed to change both of them  
for some backward compatibility purpose?

tnx!

Subject: [alsa-devel] Configure and use dmix with a new ASoC driver
To: alsa-devel at alsa-project.org

Hi, 

I don't know if there is something special I should do to be able to use dmix
with my new ASoC driver I made (TLV320AIC23b codec running on a AT91RM9200
board).

The problem is when I try to use dmix with aplay, it doesn't work and I got
this error message:

# aplay -v -D plug:dmix /media/usb0/tada.wav
aplay: main:545: audio open error: Operation not permitted
#

Listing of my /dev/snd:

# ls -al /dev/snd
drwxr-xr-x    2 root     root            0 Jan  1 00:01 .
drwxr-xr-x    7 root     root            0 Jan  1 00:01 ..
crw-rw----    1 root     audio    116,   0 Jan  1 00:01 controlC0
crw-rw----    1 root     audio    116,  16 Jan  1 00:01 pcmC0D0p


Notice I have a default /usr/share/alsa/alsa.conf file too. I'm running ALSA
1.0.15. Of course, it works well when I play a sound without the -D plug:dmix
parameter...

# aplay /media/usb0/tada.wav

armus_tlv320aic23b: pck1 started

Playing WAVE '/media/usb0/tada.wav' : Signed 16 bit Little Endian, Rate 48000

#

I tried to find some useful documentation about dmix but mainly it says that
when we have a recent version of ALSA, we don't need to configure it because
it's already done?
