Hi,
I have this very weird sound issue in SC2…
First, some backstory: A while back I got myself some noise cancelling headphones (Bose 35QC II) that I connect to over Bluetooth (via the Intel bluetooth device on MSI X470 Gaming M7 AC motherboard). Now, ever since I’ve found that I do not get any audio when playing SC2 (more to come on this). It’s kind’a weird because SC2 has always been very stable for me. When looking into this I noticed that the drop-down menu for audio devices on the sound settings options page only had a “Default” entry, nothing else, which is really weird as I usually have all kinds of output devices (like monitor speakers, the MB audio device and my ASUS Xonar). Checking with WoW I have all these devices and no issues with audio.
I tried resetting settings, updating drivers, rebooting, reinstalling SC2 - all the things usually recommended in situations where the root cause of the issue is unknown - but nothing have helped. I did notice that I sometimes got audio but could never really pin down why so I gave up, hoping for a random fix in a patch.
So, I’ve been playing SC2 without audio for some time when I discovered that whenever I start SC2 while listening to music from my PC in my Bose headphones, the sound would cut off and I would get this half-echo kind of sound - just like as if I was getting my own microphone fed back to me at very low volume. Ok, so I can’t hear SC2 nor can I listen to music while playing… This sucks!
But lo and behold! About two weeks ago I noticed that I did have a list of audio devices in the audio settings dialog - but still no audio… Crud! Clicking around in the menus, figuring that maybe - just maybe - there was some kind of interference between the in-game voice-com and normal audio I went to the “Voice” settings tab and POOF - I had audio without touching anything and I can listen to music while playing.
It turned out that the thing had not solved itself - I still have to have my headphones ON and go to the settings tab and visit the “Voice” tab for audio to work. Not only that, the only sound device that I can get working audio on is my BT headphones! Choosing any other device just gives silence with or without the headphones turned on.
Don’t advice me to reset settings - I’ve done it multiple times - nor to upgrade drivers - also done multiple times since this issue started - nor to reinstall the game - also done since the issue arose. I’m just stumped and figured I’d let you know this issue exists “in the wild”. I’m sad that I can’t play without my headphones but happy that I can at least play SC2 with sounds!
