No sound in hangouts app on CM9
Last year I rooted a t-mo S2 and installed CM9 on it as a present for my sister. Everything worked great except when I video call her using Google Hangouts, she cannot hear me. I tested it while I visited and I have tried speaker and earpiece and checked her volume. It works fine on a normal call. I did not test Bluetooth or plugged in with headphones. I have one more day here and I hope to solve it for her.
I have two questions, first of course, has anyone else had this issue and fixed it? How?
And two, last year I used an excellent S2 toolkit to put CM9 on it, if upgrading to CM 10 is the solution, is there an easy path? I don't have my laptop with me but could borrow hers. I'd like to fix it without disrupting her setup or spending all day on it.
Thanks in advance.
