Version：AVerMedia Streaming Center (Win) v1.6.53.1
OS：Win10 x64, Win 11
Supported Models:
GC311G2, BU113G2, GC553Pro, GC515, GC531, GC535, GC551G2, GC553, GC553G2, GC570D, GC571, GC573, GC575, GC311, BU113, PW310P, PW313, PW313D, PW315, PW513, PW515, AM310, AM310G2, AM350
Description：
1 Fixed an issue where multi-channel audio info might not show when opening Streaming Center with GC553G2.
2 Solved a problem where turning HDR on/off or opening/closing Streaming Center could sometimes cause the video to stop displaying or the audio to act abnormally.
3 Fixed a bug where a “Please connect AVerMedia device” message might randomly pop up when starting Streaming Center.
4 Improved scene transitions smoother while recording.
5 Fixed an audio issue where stereo or 5.1 channel sound could be incorrectly converted. Now, stereo input stays stereo, and 5.1 stays 5.1 as it should.
