FiiO K11 R2R audio issues with LO.
So, I've owned the FiiO K11 R2R for what feels like almost a year now. It has been working perfectly up until this week, where no matter what I'm playing, whether it be from Tidal, YouTube, etc, the audio will be present for the first second of play and then will drop down to an almost inaudible volume. I can tell there is still a signal because if I turn my speakers up to max volume, the audio is there but very quiet.
I have been troubleshooting for the last few days, but to no avail. I've tried everything I can think of, from trying different sample rates, different buffer sizes, different USB cables, different USB ports, uninstalling and reinstalling the driver, etc. It has become very frustrating. It also seems to be isolated to LO as my headphones work fine with the DAC.
Does anyone have any other suggestions I could try before I run this DAC over with my car?
For reference, I'm on Windows 11 with an ASUS TUF GAMING B650-E WiFi motherboard. My K11 R2R is connected via LO to a pair of PreSonus Eris 4.5 Nearfield Monitor speakers.
Any help/advice is greatly appreciated.
