Windows XP Control Panel configuration of Sigmatel Audio gives only two controls: Jack reconfiguration on/off, and Sample Rate 44.1kHz / 48kHz /... No choices for bit depth shown.
Trying to use 16 bit by some other route I did try enabling, in REAPER Preferences ASIO Configuration, "Force WDM Driver to 16 bit" - still no dice.

Previous (output not-working) setup was:
... Control Panel - Sigmatel - 44.1kHz
... REAPER - Preferences - ASIO Configuration - Shows Sigmatel 48kHz 24bit
..... and "always resample 44.1<->48kHz" enabled
... REAPER - Project Settings - Project Sample rate 44.1kHz

Notice the inconsistency above? Control Panel and ASIO4ALL have different ideas about the Sigmatel sample rate. Now I see that Windows Control Panel - Sigmatel does offer a sample rate selector. Let's try changing that ... and it works !!

New (output working) setup is:
... Control Panel - Sigmatel - 48kHz
... REAPER - Preferences - ASIO Configuration - Shows Sigmatel 48kHz 24bit
..... and "always resample 44.1<->48kHz" enabled (or not, it still works!)
... REAPER - Project Settings - Project Sample rate 44.1kHz

That still seems a bit screwy, but it works. I have tried changing a few other settings in REAPER and in ASIO configuration, and it continues to work! The one vital setting that makes it all work is Windows Control Panel - Sigmatel Audio - Set sample rate to 48kHz.

What does this mean for tetz / REALTek?
Try changing the REALTek sample rate through Windows Control Panel, and check in REAPER to see if output connections magically reappear!
well spotted! thanks for sharing
