[mythtv] RE: Re: [ivtv-devel] Stupid question

[David A. Mason]

I wonder if it has anything to do with this output, though. I find that it
is sufficient only to start mythbackend (without trying to watch or record)
to kill the sound. I.e., if I start mythbackend and stop it immediately
after, I can no longer get sound with my video using the ivtv record.pl
script.

Is this also the case with you, Achint?

Hi Isaac,

	Included below is the capture of the output from mythfrontend.

	I did notice that it says "OSS audio device"... I'm using ALSA. Is
this an 
issue ????

	Also it's probably time to move the discussion over to myth-devel,
so I am 
cc'ing that list and will continue the rest of this on that list. The 
original email is included at the bottom for context.

	Thanks to Kevin and Isaac for responding...

Cheers,
Achint

Hi Isaac,

	For the frontend, the output for the audio device is set to /dev/dsp

	For the backend, the audio device on the "Capture Card"
configuration screen is set to (None)....

	I'll grab the output from the frontend and as soon as I get home and
post it to the myth list....

	Thanks

Cheers,
Achint

Hi,

        I've installed a PVR-250 card into an ASUS pundit. I downloaded the 
latest 
driver files and got everything running.

        I'd like to thank the developpers since this part was relatively 
painless...

        Capturing video and audio using cat /dev/video0 > test.mpg works 
great....

        I did run into some issues with setting up MythTV. Basically it does

not 
produce any audio and after running the mythbackend and killing it, I can no

longer use the cat /dev/video0 trick to record audio.

        Using test_ioctl -a before and after mythbackend, does not indicate 
any 
differences.... 

Questions:
(1) Is there any way to capture the card state other than test_ioctl -a ?
(2) When I run lspci -v, I see

when according to the Myth FAQ I am supposed to see:

        Is the fact that I don't see " iTVC15 MPEG-2" an issue ? Do I need
to 
swap 
the PCI slots ??? The weird part is that it works fine before I launch 
mythbackend.

        Thanks in advance

        Incase it's relavant, the machine is an ASUS pundit with a 2.4ghz
CPU 
and 
1gig of RAM, running gentoo (2.4.20-gentoo-r5). I've checked on v4l2 support

and the patches listed in the readme files and the kernel is patched.

Cheers,
Achint
