No sound from PC after adjust metronome volume in X1. *FIXED*

Started a new project trying to record an acoustic project. The mic was picking up the metronome from my headphones so I lowered the volume on the metronome bus and did some quick test. Out of the blue the metronome stopped putting out sound like it was muted. I raised the volume back to 0db and it started working. I lowered it again to around -8db and all of a sudden I got no sound output at all. None of my projects in X1 will produce sound, Windows Media player and Winamp put out no sound either. I tried reloading my drivers and that didn't help. If I open up X1 and enable input monitoring, I hear what I'm playing over my headphones and monitors but nothing else puts out sound. Right now I'm dead in the water ...

WTH? Any thoughts on this short of a format/reinstall? :(

For the record, I never had issues with the maudio profire 2626 and win7 64bit. the Fast Track can be a little wonky, but I thought I'd seen someone else report this problem with the metronome. It works fine for me, so I can't really comment. 

Have you tried maybe changing the metronome sounds? It's a stretch, I know. Never know.

It almost sounds like you have a gate on the metronome. You could try routing the metronome direct out your outputs instead of through the master bus and see where that takes you.

I have/had similar issues..
metronome would only work sometimes.. (latency@1024 and midibuffers@1200ms), the system was pretty stressed and I had to globaly disable the effects to record new tracks. sometimes the metronome would be clearly audible during recording, sometimes it would just stay dead silent. I think I lowered the volume on the metronome as well..

I also had some weird and annoying issues with my audiointerface, it would stop working with windows mediaplayer and so on, while it would still work in Sonar! (ok, a bit different than the OP scenario). I tried all kinds of stuff to get rid of that behaviour and it seems that only and finally some rme beta drivers got rid of that annoyance! I come to believe that some windows updates messed up the soundconfiguration. I found another rme user with the same problem and I wouldn't be surprised if this problem is not only limited to rme users.
I'd guess that a windows-backgroundapplication blocks an audiochannel,.. the audiodriver can't access the same audiochannel at the same time: silence! RME and their new beta driver can now dynamically access the same audiochannel, which means that 2 applications share the same channel but you still get sound.

Thanks for the update Bub.  Was you on an old driver or the current one.  Just curious for future refernce.  Im running the FTU as well.
