I currently use a Creative Soundblaster Z soundcard in my Win 10 64bit PC. I’m running it in a 5:1 external speaker setup. Over the last few months I’ve started having an issue with the sound being swapped to different channels, for eg Centre changing to SubWoofer, LF becoming RR, LF changing to no sound at all, and RL coming out of the centre speaker. It happens completely at random as far as I can tell and it’s most noticeable during YouTube videos. It also happens during games - it might also happen during DVD playback, but I don’t use it often enough to be sure. A temporary fix is to open the SB Control panel, switch the output slider from speakers to headphones, pause a second, then slide it back. This restores the correct channel output until the next time. Which might be next day or 10 mins later or anything else at random. I have checked and I have the latest drivers from Creative - although they are a couple of years old now as this soundcard is now on Creative’s “legacy” list.
Has anyone else experienced this or has any idea what might be causing it, and more importantly, any clue how to stop it. Although not critical, it is annoying, especially those times when it happens several times in a session.
Any help gratefully received. Thank you.
