Am I at a point now where I can try to get alsa-lib and alsa-util in place? If so, what version? I found some tars at:

http://www.alsa-project.org/alsa/ftp/lib/

Is that the best place to get them? I am using buildroot, but not sure if ALSA stuff is ready for primetime there. I guess I should check on this asap.

Afaik, there is an issue with buildroot atm (please someone correct me if it's now fixed) when it comes to building alsa-lib for ARM. (please search archives for details).

No, I think you are right. I have tried a few recommended patches, but they do not work.

Fwiw, I use openembedded for all my embedded builds without any problems

atm. http://www.openembedded.org

At some point when I have some time, I am going to give it a try. I have managed to build the libs and have those in my rfs using:

CC=arm-linux-gcc ./configure --host=arm-linux --prefix=$HOME/buildroot/build_arm/root/usr --with-versioned=no

...and then...

make install

With this, I get the /usr/ entries in my rfs. However, I have had troubles building alsa-utils. When I try:

CC=arm-linux-gcc ./configure --host=arm-linux --prefix=$HOME/buildroot/build_arm/root/usr --with-versioned=no

I get:

Not sure what is the problem here. I have

file:///home/grhuser/buildroot/build_arm/root/usr/lib/libasound.so.2.0.0

in my rfs. Any suggestions?
