Hello,

 

I am working with BF537-Stamp, AD1836AZ codec, rev. B.

Linux-2.6.28.9-ADI-2009R1-pre

 

root:/>  cat /proc/asound/cards

0 [ad1836         ]: AD1836 - ADI ad1836

                      ADI ad1836 at PF4 SPORT0,rx/tx dma ch:3/4,err irq:45

 

During sound tests I see the following issues:

1. OSS i/f works OK - (tone, vplay, vrec, vrec | vplay)

2. Regarding to ALSA i/f :

   2.1  aplay -D default sample.wav - OK

   2.2  aplay -D ad1836 sample.wav -

ALSA lib ../../../alsa-lib-1.0.18/src/pcm/pcm.c:2202:(snd_pcm_open_noupdate) Unknown PCM ad1836

aplay: main:550: audio open error: No such file or directory

   2.3 arecord -D default a.wav

Recording WAVE 'a.wav' : Unsigned 8 bit, Rate 8000 Hz, Mono

arecord: xrun:1094: read/write error, state = RUNNING

   2.4 arecord -D ad1836 a.wav

ALSA lib ../../../alsa-lib-1.0.18/src/pcm/pcm.c:2202:(snd_pcm_open_noupdate) Unknown PCM ad1836

arecord: main:550: audio open error: No such file or directory
