Hans, FYI:
I just tried to set Paul's "good start" settings (post below), not through Terminal, but through the QMX menu. After finishing, selecting the right push-button to step out, my QMX locked-up with just "Audio" showing. No buttons worked including power off, so had to power off by pulling the plug.
On re-start (plugging back into power and starting), QMX came up just normally, and all settings I made were still present.
I was able to reproduce the issue (again, Menu settings via QMX, not terminal) by trying a few things. This is what did it in:
- moving "Sample blocks" back up to 5 (your originally published settings to try)
- backing all the way out of menu. (QMX working OK here)
- returning to Menu -> Audio -> AGC Settings -> Sample blocks
- reducing the Sample blocks to "2".
- back -> back (to AGC Settings) -> back (to Audio)
- QMX totally hung now
Something to do with reducing the value of Sample blocks appears to make QMX grumpy.
