PC won't play through audio setup
Hi, please help me get our school's audio equipment up and running!
I'm a primary school teacher in the UK. We have a new setup in our hall which includes mixer, amp, CD player and PC.
The mixer has 6 channels, everything is working fine except I can't get the PC to play it's audio through it. I connected to the remaining channel using a cable that connects from the headphone socket to red and black jacks which go into the mixer.
This doesn't work. The cable is fine, it works on a similar setup in my classroom. I swapped it to the channel where the CD player works, no joy. I tried a different laptop, no joy. Windows 7 and 10 tried, nothing plays through this setup. It does work through some mini of speakers however.
This is driving me mad, what am I doing wrong?!? Please help.
