This has been troubling me for a few months already. I have a VIA M1000 that is using minimyth 18.104.22.168 for a while now. The box is connected with the tv with a VGA cable and an audio cable from the onboard audio card to the tv. This worked ok for quite a while, the audio level of the minimyth box was a little bit lower than that of the tv signal, but no too much. Untill a few months ago when the audio level dropped significantly. I have to turn the volume on the tv up to about 80% to be able to hear anything.
When I telnet into the minimyth box, amixer tells me that the master volum control and the pcm volume control is at 90%. Turning that up results in distorted audio.
The recording level on the backend is (and was) at 90%.
Does anybody have an idea what to look at?
I have two PVR-250s in my backend. With different versions of the driver, the PVR-250 has recorded at different volume levels. For a period of time, the volume level was significantly less than the volume level of the tv signal. Thankfully, the newer versions of the driver have fixed this for me.
