all is ok but
1> 0ch - 3ch
capture / playback both pass
2> 4ch - 15ch
can not capture / playback
why ?
then i check tvp5158 audio driver
found
static u8 cascade_id[] = {
0x5c, 0x5d, 0x5e, 0x5f,
};
this is i2c address of tvp5158 on DVR platform
then i changed it to EVM 's i2c address
static u8 cascade_id[] = {
0x58, 0x5c, 0x5a, 0x5e,
};
but ch4 - ch15 also can not work
why?
thank you for any help
