No audio with MythTV

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



My setup is 3 machines all running Fedora Core 6 with 2.6.18 kernels.

Machine 1 is my laptop where I want to run mythfrontend.
Machine 2 is where I want to run mythbackend.
Machine 3 is where I am running MySQL.

I have compiled MythTV on m/c 1 and m/c 2 from source.

I have no problems with running this setup as far as video is concerned 
for DVB-T (I haven't yet tried composite or s-video) - everything works 
fine.  My problem comes with getting any audio at all.

I suspect that my problem might be with the capture card.  It's a 
LifeView FlyDVB-T Duo PCI and does both analogue TV and digital TV 
capture as well as composite and s-video capture.  The chip on the card 
is a Phillips saa7134.  The card has two connectors up in one corner. 
One is a 4 pin Molex type connector and is marked "CD IN" (I'm guessing 
that the purpose of this is obvious).  Next to it is a 4 pin connector 
that I think is an SB type connector and it is marked "AUDIO OUT".  The 
card came without any card to motherboard cables and in the doco 
(Windows only naturally) makes no reference to any cabling from card to 
motherboard, but I suspect that such a cable is necessary.

I do know that the sound systems work fine on both m/c 1 and m/c 2 under 
other circumstances.

So, my questions are:

1. Do I need to cable the sound separately, or should the sound be being 
handled over the PCI bus along with the video stream?
2. What is the pin assignment for the SB connector?  I'm assuming at 
this stage that it is the same as for the Molex, namely R G G L.
3. What do I need to do to either alsa or oss on the backend machine, 
and also on the frontend machine?  I really am clueless as to how Linux 
sound works.
4. How does MythTV capture and store the sound?  Does it do that as a 
combined stream together with the video into the .nuv files?

Any clues or pointers gratefully received - I'm getting good at lip 
reading  :)
