Forgive me for bumping an old thread.
I seem to have developed this or a similar problem. I’ve checked all the external connections, but haven’t yet looked inside the PC.
However, what’s slightly different is that my call-outs are almost non-existent, and changing the mix settings has no effect. Sound effects and music are fine - and loud. Running test mode and doing a sweep I don’t hear any dead ranges, so I don’t think it’s a bad band-pass filter.
Does this sound familiar to the problem described in this thread? To me it sounded like all audio was being disrupted, or just one channel.
Thanks.
