When the speakers are actually working, if I plug in headphones, the speakers get muted and the headphones work. No need to manually select an output. > Does the laptop surround51 by retasking two mic jacks and headphone ? I don't _think_ so. AFAICS it only has two jacks - one headphone/speaker, one mic. There's no third jack anywhere that I can see. -- Adam Williamson Fedora QA Community Monkey IRC: adamw | Twitter: AdamW_Fedora | identi.ca: adamwfedora http://www.happyassassin.net
