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%.
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%?
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.
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.
