I want to play my bass guitar along to YouTube videos on my Windows 7 PC and hear the combined mix via my Bluetooth headphones. I have two problems. I have tried a tiny USB Bluetooth adapter, it works and connects to my Bose QC35 headphones, and I hear the PC audio fine, but for some reason it only plays the PC Audio to my headphones, and the bass guitar, which is plugged into the PC front MIC socket, still comes out the speakers. I'm pretty PC literate but can't find a fix in the settings. I then tried a BT adapter that is USB powered, but connects to the headphone socket for audio input. That's getting a LOT of background noise from the headphone socket. The next problem is a delay of around a second on the bass, with the bass plugged into the mic socket on the PC. PC is an i7 ATX desktop with 8GB RAM so it's quite pokey, but I'm obviously going about this the wrong way.
Will a cheap USB guitar input box like the Behringer UM2 work for this? Or a separate sound card? I don't want to record, and as long as the sound is clear and not noisy, with no latency, I don't need to tweak it. All I want to do is play along to YouTube videos on my PC and hear both the video audio and the bass guitar through the BT headphones only. Without spending a fortune :). Thanks in advance.
