Audio issue while resampling audio from 2ch to 8ch #17

Open kurt-k opened 3 years ago

Hello together, i've problems with my Logitech G533 USB wireless headset and linphone on Windows 10.

When i try to play the testsound or start a call, the audio contains only terrible cracking.

When i select a 2 channel output device like my monitor, the sound is perfectly clear.

I had a look at the logs and the only difference between the to cases that i can see, is the resampling from 2ch to 8ch audio. Is this a know issue and can someone help me?
