Can't use S24_LE format to record audio with adau1361 on bf537-stamp.

I found this on 2011r1 branch and 2011R1_ADAU. This bug looks similar to me as bug [#6739].

Could this be a SPORT issue?


Do you know what the fix was for [#6739]?


--- Scott Jiang                                              2011-11-15 21:58:29

Hi Lars, it's caused by alsa config file. If you use aplay -v, you will find

plugins don't work.I have told Mark Brown to fix it, so you must modify all adau

config file in alsa lib.


--- Lars-Peter Clausen                                       2011-11-16 02:50:47

Scott, we don't have any adau config files. I think this is a problem with the

SPORT and 24bit playback/record.


--- Scott Jiang                                              2011-11-16 21:55:38


ls |grep ADAU





--- Lars-Peter Clausen                                       2011-11-17 12:55:33

oops. i was only searching for lower case adau, sorry.


But this bug is still a problem with the SPORT ASoC code.


--- Sonic Zhang                                              2011-11-25 02:38:19

Vivi update name in adau1361 alsa conf


--- Vivi Li                                                  2011-12-02 04:06:36

Hi Lars,


The sound card name is too long and is cut to "bfin-eval-adau1". ALSA

plug-in will fail to work. Could you fix that?


root:/> cat /proc/asound/cards

0 [bfinevaladau1x6]: bfin-eval-adau1 - bfin-eval-adau1x61





In other boards such like ad1836, we have shorter name:


root:/> cat /proc/asound/cards

0 [bfinad1836     ]: bfin-ad1836 - bfin-ad1836




--- Vivi Li                                                  2011-12-15 02:43:42

Now device name is modify to eval-adau1x61 by Lars in 2011R1 branch. Accordingly

I update card name to eval-adau1x61 in alsa conf in 2011R1 branch.


root:/> cat /proc/asound/cards

0 [evaladau1x61   ]: eval-adau1x61 - eval-adau1x61



root:/> cat /usr/share/alsa/cards/eval-adau1x61.conf

eval-adau1x61.pcm.default {

        @args [ CARD ]

        @args.CARD {

                type string


        type asym

        playback.pcm {

                type plug

                slave.pcm {

                        @func concat

                        strings [ "dmix:CARD=" $CARD ]



        capture.pcm {

                type plug

                slave.pcm {

                        @func concat

                        strings [ "dsnoop:CARD=" $CARD ]
