You seem to have a problem with I2C communications. Is this a custom board? Which software are you using? Where is codec connected? Have you checked I2C traffic?

Yes it's custom board(SBC8600B). I use kernel psp04.06.00.11 and from vendor with modifictaions(linux-3.2.0-psp04.06.00.08). I don't know where is codec connected. Vendor can't help and I don't have time to send board back to vendor.

Can you tell me how monitor I2C trafic and detect codec connection?

Thanks.

I don't see how you can detect by software. You should have a PCB schematics to determine board connections.
