Topic: RME UCX: distorted sound, harsh sound - finally reproduced
Hi,
Interface: RME UCX Fireface connected via USB;
System: Windows 7 64bit SP1;
Latest RME UCX drivers/firmware;
From time to time i got the distorted sound/harsh issue from my RME Fireface UCX, but i was unable to reproduce it constantly, unable to find the dependence on it's occurrence, even sent an email to official RME support for a known issues - but got a reply, that the drivers are stable, no known issues on distortions/harsh sound found.
Finally now i can reproduce it on demand:
So if you run any non-ASIO driver application in windows and start playing an audio - for e.x. start playing some song in Spotify or Winamp, then while still playing audio go to your "Fireface USB settings" and change "Buffer size" to any different value than the currently set, save setting, so the audio from Spotify or Winamp is still playing without any issues, then open some application which uses ASIO Fireface USB driver (e.x. - Ableton, FL Studio and etc). Then the audio from the non-ASIO driver application (Spotify or Winamp in our case) will start to harsh, gets distorted and etc. Even if you close the Ableton now - the audio will still be distorted in all Windows environment. Sometimes only restart helps.
Please check this and advise.
I could capture a video if needed to show all the process of reproducing.
