What steps will reproduce the problem?
1. Sony Vegas 11.0 (build 683) 64-bit / Win7 64-bit
Project Settings/Audio -> set to: 16bit/48kHz/Stereo 

2. In the "Render As"-menu in Sony Vegas, the audio properties for DebugMode 
Framesever shows as 44 100 Hz/16bit/Stereo. That seems to point in the 
direction that the the audio has a wrong sample rate already at this point?

3. Trying to create a Quicktime ProRes video thru FrameServer by using ffmpeg 
-- ffmpeg also detects the Frameserver stream's audio as 44.1kHz instead of 
48kHz. Only way to override this is to use the "-ar 48000" switch in audio 
encoding which will forcibly resample the stream coming from frameServer @ 
44100 to 48000 kHz. No audible flaws in the audio in output file, but the 
sample rate mismatch is a bit worrysome considering exact audio sync?

What is the expected output? What do you see instead?

Expected to be able to render audio as 16-bit/48kHz, but the stream seems to be 
44.1kHz, regardless of the project audio settings being set to 48kHz.

There was another user asking this same question, his/her problem seemed to be 
related to Ripbotx264 (see: Issue 20) - or maybe he was mistaken and there 
really is a problem creating a 48kHz audio stream from Vegas 11?

What version of the product are you using? On what operating system?

Latest version of FrameServer & Sony Vegas 11, both 64-bit.

Please provide any additional information below.

Any help highly appreciated! Thanks for the great software!
