Other Parts Discussed in Thread: TLV320DAC3203

I'm using TLV320DAC3203 now.

But, I can't find linux driver for this device.

Would you share the linux driver?

Thanks.

    Hi Jake,

    The best  course for a design using the DAC3203  on a Linux based system  is to use the opensource driver already available  in any recent Linux kernel.  Please look for  sound/soc/codecs/tlv320aic32x4.c.   While it was originally designed for AIC3204, this driver can support all the features available on the DAC3203 as well.

    Regards,

    hari

    Hi,

    anyone have success using sound/soc/codecs/tlv320aic32x4.c driver with TLV320DAC3203 codec ?

    In my application, after first inizializzations, the codec put SDA Low and block the bus. Only codec hw reset, unlock the bus.
