No. I tried to start a pledge to get someone to develop it, but it 
didn't generate any interest. What I did was a bit of a hack, but it 
works for me. I have 2 PVR-250's, a PVR-150, and an HDHR, the PVR150 is 
significantly quieter than all the other tuners (by 12db, if I recall 
correctly) so I commented out the code in Myth that sets the volume, and 
I manually set the volume for each PVR card at boot time (quiet the 
250's and raise the 150) and the volume levels are pretty much bang on 
now. The HDHR records the audio at whatever the stream contains, so 
there is nothing you can do there, but it appears that the audio levels 
are fairly consistent in the digital recordings I am getting.
