i have successfully installed rc7 (many times) and everything works like a charm except that the audio coming out of the pinnalce pctv is white noise.
note that i connect the speakers directly on the tv tuner card and get broken sound while video is fine on a channel.

i did some forum reading and googling to find out that probably my cheap tv tuner card has no support for btaudio meaning that i have to use the audio out on the tv tuner card to get sound. i did not find how to debug the problem.


is there a chance that i did not select the correct setting for tv format? or channel type? (europe-east,europe west.. etc)

thanks for the great project and friendly forum :)

the following lines are from dmesg

bttv0: i2c: checking for MSP34xx @ 0x80... not found
bttv0: i2c: checking for TDA9875 @ 0xb0... not found
bttv0: i2c: checking for TDA7432 @ 0x8a... not found
tda9887 @ 0x86 (bt878 #0 [sw])
tuner 0-0060: chip found @ 0xc0 (bt878 #0 [sw])
..
registered video0 & vbi
...
bt878: AUDIO driver version 0.0.0 loaded
bt 878 AUDIO function found (0).
are those two bad news?

i guess it is normal not to register a sound device since no audio is coming from pci bus, but for some reason the audio output is messed up. i checked the card on win machine to be sure it is not broken. anyone any idea?

I have seen the bt878 driver load with;

bt878: AUDIO driver version 0.0.0 loaded
bt878 AUDIO function found (0).

And the audio worked. I don't think this is a bad thing. Can you post your dmesg output. What is your tuner type? PAL/NTSC-M?

this should help a lot:
i just finished a mythdora installation and also did not touch anything.
i did the same configuration on myth-setup (pal ..etc) and the audio is working like a charm overthere.

i noticed that the same autodetection takes place and by looking tha dmesg i noticed that the line:
tda9887 0-0043: chip found @ 0x86 (bt878 #0 [sw])
is missing from mythdora. so i'm thinkin if i block this at knoppmyth i should have audio coming out of the jack just like mythdora.. right?

i really prefer debian based distros so please help! :P

thanks again!

i am desperately trying to get the line tda9887 chip found out of my dmesg output.

i try
rmmod tda9887
update-modules
depmod -a


but dmesg has tda9887 again. can someone please tell me a way to trick that autodetection NOT to look for tda9887 chip (that i most likely do not have and gets mystiriously detected)

i think i am pretty close plz help me!

:cry: :cry: :cry:
