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

-rw-r--r--    1 root     root            0 Jan  1 01:51 registers

looks like  I am missing another 3 things which should be

<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.
