I am trying to fix my Mom's computer speaker issue. I have been to the control panel>sound, and the computer speakers are selected, and they "test" OK (I can hear the "bell" sound). The volume is also on max. according to the speaker icon on the bottom Left of the screen. No mute buttons are on. Both the Intel & Sigma Tel systems indicate they are up to date & functioning properly. Diagnostics tested out OK as well.
However, when attempting to play music, you tube videos, etc., no sound can be heard. Any ideas for what I can try?
