Hello Keith,
This is a quick link to my standard troubleshooting list.
These two tips in particular seem most relevant to your case:
- Try setting FxSound as the Default Communications Device (this actually sets FxSound as both the Default Device ànd the Default Communications Device simultaneously, but only shows it as the Default Device);
- In Windows Sound Settings, disable all the devices you don’t need, including the hidden ones (the Dell monitor, in this case).
Please let me know if this helps.
