We are using the TPS65950 on a custom designed board that shares some similarities with the BeagleBoard. Otherwise the TPS65950 is working quit ok but the sound via the IHF channels is very distorted. We have checked our schematics and PCB layout for errors. The speakers sound ok with external amplifier, also the head phones (connected to the tps65950) sound ok.
We have also tried to filter out the frequencies below 700Hz which improves the sound quality a bit.We have also tried a lot of different combinations for the mixer settings (using alsamixer), The processor we are using is a OMPA3503.
Do you have any pointer as to what to check?
