Hello! I recently obtained a BOSS GT-1000CORE [0]. It has the capability to act as a 6-in/6-out USB audio interface. Thankfully, Linux seems to detect it correctly without any configuration, and I see all of the inputs and outputs that I'd expect in Pipewire: https://ataxia.io7m.com/2023/01/14/pipe.png Unfortunately, there seems to be some kind of odd distortion. This is a capture of a raw DI signal from the BOSS: https://ataxia.io7m.com/2023/01/14/noiseissue.flac There's something odd happening in the high frequency range. It almost sounds a bit like some kind of resampling artifact. The same distortion is not present if I plug headphones directly into the BOSS, so the distortion itself evidently isn't happening on the actual device (or coming out of the guitar pickups!). Does anyone know what could be causing this and/or how I could track it down? $ uname -a Linux sunflower.int.arc7.info 6.1.1-arch1-1 #1 SMP PREEMPT_DYNAMIC Wed, 21 Dec 2022 22:27:55 +0000 x86_64 GNU/Linux [0] https://www.boss.info/uk/products/gt-1000/ -- Mark Raynsford | https://www.io7m.com
