Say, I have a laptop, a desktop, and a headset.
Instead of investing $40 on a dedicated mixer, I was thinking of buying a 3.5mm male-male aux cable and pass through a slave(desktop audio out) to the master(laptop microphone audio in) to my headset.
Sound coming from desktop(slave) will be limited to notification(facebook messenger, email...). Sound coming from laptop(master) will vary(music, youtube...)
Here are my assumptions.
- This method will work with some sound deterioration.
- Sound source coming from master won't deteriorate.
- Sound source coming from slave will emit continuous(?) noise, thereby the mixed result will have continuous noise.
- Slave will be mono, master will be stereo.
Am I correct on all these assumptions? Are there more disadvantages of my method.
