winniedixie Posted November 17, 2008 Share Posted November 17, 2008 Hello I have a Dell Precision M90 with a Sigmatel 9200 After a lot of work... now I can hear sound but the headphone is not recognized... I hear the same from speaker and from headphone. I'd like to manage headphone separately from speakers... I prefer to hear by headphone and not from speakers... This is my last chance !! If anyone can help me... please !!! Thank you in advance.
