Upsampling beyond 96khz leads to continuous crackling/noise and playback in low speed

Maybe this will help you. If not search the forum for Fritzbox there seems to be quiet some issues

Titles Skipping constantly [resolved - deselected the Package Accelerator in Fritz Box]

Hi @wklie, Thanks Peter. I have/had the same behavior (tracks/titles skipping) with a Fritzbox 6490 and now 6591 - of course both Fritzboxes. If I disable the Packet Acceleration the speed drops from 500-900Mbit/s to 10-30Mbit/s and if I reboot the router everthing is back to standard (with Paket Acceleration). I opend a support request at AVM (Fritzbox). Thanks for trying to help.
