So I've got the Logitech Z-906 speaker system, and I've had it for a while. When I listen to certain songs through iTunes, with the same equalizer settings for all scenarios, I experience high pitched "crashing" noises through the speaker system - regardless of volume. If I play the SAME audio file through my Logitech G35 headset, instead, I get BETTER sounding audio AND no crashing sound. As some might know, the G35 headset should -NOT- provide superior audio quality versus the Z-906 5.1 surround sound speaker system. I'm using an optic cable to connect my speakers to my computer.
I've never had a dedicated sound card - although I figured buying one would fix this issue. The problem, however, is that I've always used onboard motherboard sound and, just recently, I purchased a MUCH newer and substantially "better" motherboard and I am still experiencing these issues - despite the definite increase in onboard audio quality that should be present.
That being said, I really want to fix this problem. I've actually had the entire speaker system replaced by Logitech and, unfortunately, that has not helped either - so the problem is not the system itself, I hope.
Will a dedicated sound card fix this problem? I'm very reluctant to drop the money on one unless there's a very good chance, given the circumstances, that it is going to eliminate the speaker "crashing" sounds and improve sound quality to, at least, beyond the level of my G35 headset.
