I recently reloaded my PC.  The CD for the CSR Harmony 4.0 driver got scratched and doesn't work.  CD came with Wavlink Bluetooth dongle I bought in Dec. 2018.

I've been trying to work with Wavlink on this.  They keep sending me links from other sites that don't work.  I can't just keep downloading 400+MB files.  One was a .rar file that my PC can't open.

Meanwhile, I bought a new dongle to have a new CD.  The driver is terrible.  Music thru bluetooth headphones sounds a little gargled like from a partially wrinkled cassette tape.  2018 driver was perfect.

I know it's the driver because I initially downloaded a Realtek audio driver that made music to stereo sound tinny.  I then found the correct driver by adding in my PC in Google search bar and downloaded it from Dell.  It works great.

So, I'm coming here for any new ideas.  Hopefully somebody knows something that works.

Many thanks.
