Hello, i use pda model o2 xda mini s,the main problem is audio does't work, but i attach headphones it works can you figure out what's the problem,it's, some time work's some time not. including mic and hear speaker..
It sounds as if it could be a hardware or software issue...it's hard to tell. It maybe a common problem though, so it maybe worthwhile to check the manufacturer's support site for answers or even get in touch with them.
