Message: 35631 I find the problem is missing something else
when I do command ls -l /proc/asound/ad1836/
it shows :
-r--r--r-- 1 root root 0 Jan 1 01:51 id
-rw-r--r-- 1 root root 0 Jan 1 01:51 oss_mixer
dr-xr-xr-x 3 root root 0 Jan 1 01:51 pcm0c
dr-xr-xr-x 5 root root 0 Jan 1 01:51 pcm0p
-rw-r--r-- 1 root root 0 Jan 1 01:51 registers

<pre class="code">-r--r--r-- 1 0 0 0 id
-rw-r--r-- 1 0 0 0 oss_mixer
dr-xr-xr-x 3 0 0 0 pcm0c

How did you compile the audio driver? (statically into the kernel or as a module?)
There should be some help at:

Message: 35633 I tried both way first as a module then into kernel but no success.
I was following the instructions per the website : http://docs.blackfin.uclinux.org/doku.php?id=ad1836a_setup
It seems that the spi bus is not being offered under drivers my only selectable SPI options are :
< > Bitbanging SPI master │ │
All other SPI options are unavailable to me under the SPI menu option.
For Character devices, I have the following two SPORT / SPI related options set :
[*] Blackfin BF53x ADSP SPI ADC support
[*] Blackfin BF53x SPORT support
I am using svn version 3174 of the linux-kernel.
thanks,
pengcheng

Message: 35802 did you enable all of the backwards OSS compatibility features in your kernel ? mp3play only works with the old OSS interface, not the new ALSA interface

Message: 35803 also, make sure the simple `tone` application works before you try testing with mp3s

What is your kernel version? Audio Driver? Are you using mp3play? We need all the information to reproduce.
