I have an "interesting" problem with msp3400.c I'm working on a Hauppauge WinTV PVR-250 which uses an MSP3435G as its audio processor. I have been able to attach the 250's i2c bus via i2c-algo-bit and load tuner.o and msp3400.o which (more or less) recognize their respective periphials. Problem #1a. Apparently the 250's audio path is somewhat different than other Hauppauge cards: The 250 uses ScartOut1 instead of the loudspeaker output. It needs to feed the audio back to the compression engine so that it can be embedded into the MPEG stream. Msp3400.c assumes that the output is via the loudspeaker (or headphones). To set up ScartOut1 fot the 250's routing the ACB needs to be populated with 0x0c00 whenever AUDC_SET_INPUT(AUDIO_TUNER) is received. The msp3400c_set_scart(client,SCART_IN1_DA,1) call will do it, but nothing triggers that. Problem #1b. The ScartOut1 volume can only be on or off! While a Prescale value of 0x1900 (0db) and an "on" volume of 0x4000 (-50db?) is workable, if adjustments are necessary, this can make life difficult. Are there other cards out there that use the msp34xx series that could benefit from a flexible method of mapping the inputs and outputs to the audiochip.h enumeration? Thanks, John
