My new M3 is generating serious distortion via both usb c ports and onboard speakers. Audio is reminiscent of blown speakers. Not crackling or static, but distortion. Most obvious in bass and sub bass, making use of headphones or IEM's a non starter. I use an outboard DAC(IFI go bar) and IEM's that play nice with my IPhone. Is this a known issue with the M3's? This happens with no other apps running so I don't see it as a memory problem/conflict as I've read in other forums.
