Windows 10: USB webcam mic: all bass, no treble

Windows 10 Home 20H2 x64 Ethernet ~ 50mb/s Sudden audio problems with all USB webcam mics. This is confounding me, I'll try to be as concise and clear as possible: 1. I was using an old MS LifeCam for Zoom/FB videochat and while video resolution was low and choppy (known and expected) the audio was fine, clear and tonally balanced 2. As I write all system sounds, audio files, videos, etc playback with normal (correct) audio thru external speakers 3. Earlier today I inherited a generic USB HD webcam+mic with 2mb pix / 1080 video 4. I plugged it in to check out and while picture quality is great, audio is terribly distorted: all bass, no treble -- muffled, like speaking through a diving mask underwater from a thousand miles away 5. Thinking this was a defective device I plugged the old LifeCam back in and found it too was now distorted -- identically -- all bass, no treble, impossible to use I have no idea what happened -- all non-cam-related audio is fine (unchanged) but suddenly the USB mics are not working well at all. I've looked through what settings options I know of, tried updating drivers (none available) and now I'm just weeping in the corner. Anyone have clues? leads? advice? !pleH

how to adjust bass & treble on speakers

How do I adjust bass & treble on speakers

 

audio windows 10--can't adjust bass/treble sound

I can't adjust or find a way to adjust the treble/bass control on my PC since my grandson used my older pc windows 10 system to connect to his smartphone for audio streaming. all devices and drivers and updates seem to be fine and all troubleshooting apps
i've used find no problem. However, the sound is 90% bass and little treble and it's very difficult to distinguish speaking voices. I can find no "older time" bass/treble mixer adjustment control anywhere on my system.

 

Can I individually control bass and treble on this computer?

Can adjust bass and treble individually on Windows 10 ie.. equalizer?
