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
