Hi, Sound is like transformed to low frequences and is very murky and distorted when I’m trying to record a voice with the optical digital in on my Mac Pro 2012 using Toslink.
I tried the sound/Midi settings app to configure my ports. However, the optical digital in seems to be stuck at 44.1 kHz sampling. After a change to 48 or 96 kHz, it resets itself to 44.1 kHz within a few seconds no matter what I do!
I use a small RCA to Toslink adapter to convert mic amplifier to digital opto. If I plug out the Toslink and plug it in again – the first 2 or 3 seconds will make a normal sound then it always distorts to low pitch and murky.
If I plug the adapter into a MacBook Pro (with a Toslink) 3.5 mm adapter the optical sound works great!
Could it be a fault in the Mac Pro optical digital input?
Why isn’t it possible to select 48 kHz sampling for the optical in?
Thankful for any ideas about this.
