Hello, you all!

sorry I have to repost the message by spliting in three ones as the original size is a bit too big to be passed.

I am facing a strange problem on our arm-based box runnig ubuntu.

firstly the following tests worked fine:

arecord -f S16_LE -D plughw:0,0 -r 8000 | aplay -f S16_LE -D plughw:0,0 -r 8000 arecord -f S16_LE -D plughw:0,0 -r 16000 | aplay -f S16_LE -D plughw:0,0 -r 16000 an so on up to 32k,44k,48k., and for c1, c2

but using Mumble's Audio Tuninf Wizard to test speaker, I could only hear my voice with very lower tune than my normal, and when I use Linphone to do the same test I heard my voice with very higher tune than standard.

in Mumble's test I used the following setting:

Audio Tuninf Wizard: input Device This is the device your microphone is connectedto. System: ALSA Device: [hw:CARD=AMLCS42L52,DEV=] AML-CS42L52, Direct hardware device without any conversions or [hw:CARD=AMLCS42L52,DEV=] AML-CS42L52, Direct hardware device with all software conversions

if I select any Pulse options I could hear nothing except choppy sounds.

I am puzzled if the problem is in kernel driver or alsa or pulseaudio? any advice appreciated.
