Hi, I recently had issues playing big audio files, 1h files, approx. 700-900MB. I can’t seem to play them anymore without hearing annoying interference. It is like a digital scratching, beeping, robotic sound. The files are my own mixtapes made in WAV and converted to Apple Lossless. Or Mix CD’s, the tracks joined together. Audirvana Priority is on “Extreme”. Is there a solution?
I also hear this distortion in the music when I am using the Safari Browser. What to do?
Hello @Rudidepudi,
Can you send me a copy of the “Debug Info”? You can get it in Audirvana Settings>General>Debug Info
Note: By clicking on the Debug Info button, Audirvana automatically copies all its content, all you have to do is paste it in response to this message

Can you disable upsampling in the audio output setting and try to play your song again?
Yes! Looks like that does the trick. Can’t hear any disturbance now. Happy!
Thanks, Rudi
Just curious, what’s upsampling do? In other words, what do I mis by disabling it? (it solved the problem!). Thanks again. Rudi
Upsampling is preparing the music to be sent to your DAC, which means it upsample it to the frequency you want. It happens that some DAC do not support it properly as it’s a process that is handled by the DAC. In your case you set it as max frequency, if you do want to try with a different setting like power of 2, you could potentially use upsampling without having issue. You then need to try it yourself.
