I've just got MythTV working and encountered something strange. Whenever I start the TV part of Myth, it resets the computer's master volume to 70%, which is too quiet for me to be able to hear - I have to then use aumixer to put the master volume up to 100%, and even then it's a little on the quiet side. This is all with MythTV's volume (as controlled by F10 & F11) set to 100%.

So,

1.) Why is MythTV setting the output to 70% when it's started? Is it possible to change this behaviour?

2.) Is it possible to boost the volume of MythTV beyond it's internal limit of 100%?


Cheers

1. There is probably something in the preferences to do this, although the easiest thing to do get speakers with amps included.
2. Of couse its impossible to have a volume over 100%. The definition of 100% is maximum

1. I've got speakers with an amp, but it's still a pain when Myth makes the volume quieter at starting and then I have to go and reset it. I've looked all through mythtvsetup but there's nothing obvious, and there are no other settings for myth that I'm aware of.

2. Thought so, just wanted to make sure .

is there a direct answer to this problem? I have yet to find anything in the preferences or config files to fix this "problem," and I agree that it's a total pain in the ass.

mrchaos,

Yeah, I did eventually find the solution - and it's blindingly obvious. There's an option in the config somewhere, I think it was in the mythfrontend setup, where you can configure the initial volume for the master and the pcm channels when MythTV starts. Default value is 70% at install time. Unfortunately, there doesn't seem to be a way to stop myth from changing the volume, which is what I would like, as it usually means that if I've got any other sound coming out it starts blasting out very loudly.

HTH

haha, Yes, I found the same configuration option shortly after posting the response. Thanks for your help though!

I can't find it, I must be blind. Can someone guide me? Using Mythtv 0.19.

I'll check tonight and post back.

Found it, sorry and thanks

No probs, was just about to post the answer but I won't bother now

I found the best solution was to untick the "use internal volume controls" and use the master ALSA mixer to control volume.
