Mythtv: sound stays on
« on: October 01, 2010, 03:23:51 pm »
Hi all,

i got my mythtv finally up and running (there where some bumps installing the tv grabber :) )
but i noticed something weard:
if i stop tv, the sound stays on, i have to reboot to kill it.

i got a analog asus tuner card (TV FM 7134);
i had to run a separate cable from this card to the mainboard audio-in to get audio working.
i use the standard template in mythtv-setup for the tunercard.

anybody any ideas as how to solve this?

br,
Raymond

*edit, I missed that you are running line-in.

I believe there is a way to force it to mute line in on exit and unmute on open.


Try opening mythtv setup, and under the general sub-menu on about the fourth tab under Startup Command:
Code: [Select]
v4lctl volume mute offand under shutdown:
Code: [Select]
v4lctl volume mute on

I don't know, however, how this will affect recording a program you are not watching.

the crazy thing is that when i hit play/pause and pause a live stream, sound doesn't get paused.

I suggest using a supported tuner card, or adding code to mute the tuner card channel.

Please, guys. It's important, when you first set up a system, to use supported hardware!

Yes, even if you got it to mute when you paused, the sync would be off. In fact, I would think the sync is off now... because the image buffers a little bit and you are just getting a raw audio feed.

sorry, but i am fairly new to all of this, the card uses the standard v4L driver and therefore i assumed it was supported.
it was recognized by the system immediately, no problem.
so this still isn't supported hardware?

thats right sync is a bit off, is there anyway to solve this?

thanks all,

Maybe... if you feel bold...

Saa7134-alsa should give you audio over cable... but it is duct tape... and recompiling that kernel might break stuff. Should give it a shot and work on making a template so it is plug and play in the future.

as you suggested, i got myself a Hauppauge WinTV-PVR-150 low profile card, this card works great.
thanks all or your help.

maybe i am going to use the asus TV FM 7134 card for analog security cams.
