Question about CSL USB sound card 7.1 Surround, external, for up to 8 speakers, Dynamic 3D Surround, driver

Unfortunately, I cannot say anything about this because I use the sound card on a PC with Microsoft. We make multi-play recordings in a group using the Audacity software and this interface works perfectly without latency, with the exception that it has a low level of "self-humming". I also use it to digitise old records, cassettes and mini-discs.
