Hi Mark,

I'm a bit lost for mixer-test and pcm-test.
Currently, I cross-compile the alsa lib project to be able to build the 
tests and put it on my board.

I can execute it, but I still have 2 issues:

1) I've a lot of missing module in my environment (Encode.so, Encode.pm, 
Symbol.pm, IO/Handle.pm, ...). AFAII, I've to cross compile the missing 
perl modules and install them in the rootfs

2) I don't know how to configure pcm-test.conf & 
Lenovo_ThinkPad_P1_Gen2.conf (or new file to match with my board).

My test cmd:
/run_kselftest.sh -c alsa

I'm wondering if I'm going to the wrong way because I don't find 
guide/readme whereas it's not trivial at all.
