Changing the sample rate on an M-Audio MobilePre
My M-Audio MobilePre has done sterling work over the years. Barely perceptable latency has made recording in music software easy (or at least limited only by my skill) and as an external box it’s easy to access all the sockets.
Only I changed the sample rate, for no sane reason, and then discovered that I couldn’t turn it back again. That wouldn’t have been a problem apart from the fact it did something unpleasant to the sound output.
Every time I opened the control panel the latency and sample rate options were greyed out. Thankfully I found a solution from the M-Audio forums here, though if you keep reading I’ll explain for Windows 7 (should work on Vista as well).
The first step to solving this problem is to make another audio device the default, or simply disable the MobilePre. I had to do the latter as for some reason the motherboard audio wasn’t showing properly.
Right-click on the Volume Control in the Notification Area and left-click on Playback devices. Right click on the MobilePre entry and then left-click on Disable. The icon will change to grey. As there were no working audio devices left, the volume control also showed a red cross.
There’s no need to close this window; it’ll make life easier if you leave it open.
Right-click on the MobilePre icon in the Notification Area and left-click on Open MobilePre USB Control Panel.
Click on the Sample Rate tab and the two options will no longer be greyed out. Select 44.1 and close this window.
Return to the Playback devices window (or open it again – I told you to leave it open) and reverse the disabling of the MobilePre. Right-click on it and left-click on Disable to remove the tick and bring the MobilePre back to life.
Simple when you know how, but very frustrating if you don’t.

End of a long mystery–thanks! (Note– you’ll need to disable the Recording tab as well).
