It's working now :-) . I kept the init for register 0 as stated above. However, the chip adress of the 4529 is 0 (CAD1=0, CAD0=0, both pins are pulled down to ground with a 10k resistor) unlike the hardwired adress of the previous chips (0x02). Also, since the 4529 has 12 registers we cannot addr &= 0x07; in snd_ice1712_ak4524_write . The faders in envy24control are still stuck at 000, but it is nevertheless possible to unmute the channels by clicking somewhere close to the bottom of the faders. Regards, Reiner PS: I need a new pair of glasses. Very difficult to contact the envy24 pins with my multimeter to verify the envy24 <=> 4529 wiring, hehe. ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf _______________________________________________ Alsa-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/alsa-devel
