Recently I ran into some issues with sound, specifically uneven volumes. Music plays mostly fine, at 100% volume. However, misc sound effects (voice and practically anything else) is quite random; it's mostly around 50% from normal, but sometimes it jumps back to normal for a while, then back again.
In practice this looks like this: I'm playing SW: The Old Republic and I'm conversation with an NPC. The music plays fine, the NPC I'm talking to speaks normally for 10 seconds, then mid-word they randomly start whispering, then back again. On YouTube, I'd be trying to listen to some podcasts, but I can't because I just can't hear them. Listening to music in the background (via Win Media Player or YT) is something I can do. However, I can't watch movies anymore on my PC anymore.
These problems came up between two reboots and I didn't do anything system-related that might have caused it.
Some more data that might be helpful:
Windows 10, 64-bit, Hungarian version
Realtek High-Definition Audio drivers are up-to-date, according to Control Panel
I tried deleting it from the Device Manager, then rebooting
The volume slider in the Control Panel and the one I can reach via ^ and clicking on the sound icon at 100%
I tried numerous presets (24-bit x kHz), but they sound the same
I use headphones (tried two), but the Control Panel recognizes them as Sound Blasters. Can't remember if that has always been such or not
Some two or three months ago, the second RAM memory slot on my
motherboard stopped functioning. Don't know if it's related, but since I don't have a dedicated sound card, and I'm using the motherboard for sound. It has worked fine forever.
