Hi,
I have a Teensy 3.6 and a PT8211 DAC.
I uploaded the PT8211Sine sketch and outputted the sound directly to my amplified speakers. The sound is nice and clean, no problem.
Then I connected the audio jack from the DAC to one of the input of my audio interface (Behringer UMC204HD). The input allows to choose between "LINE" or "INSTRUMENT". With LINE selected the signal level is to small but it is good with INSTRUMENT so I selected INSTRUMENT.
Then I recorded the sound with Audacity. This time the sound is not nice and clean at all, it is like pitched. I tried selecting LINE but I get the same pitched sound. I tried recording with Ableton but I get the same pitched sound.
Do you know what can cause this ? I thought maybe it is because the DAC is 44.1KHz and my Audio Interface is 192K but I don't really think so. I tried with all the possible preference settings from Audacity but I always get this pitched sine wave.
