Hello all, There's sound on the notebook, use dual monitors, Alsamixer on F6 selected driver on card, levels appear to be working ok, and on volume control, it detects signal to the slide meters, and shows signal at that level ok, but no detection of HDMI hardware, says unplugged!!. Fedora is updated, but no HDMI sound--appears to need source code to port over sound to the HDMI. HDMI video works fine. The Intel audio chip is working. Can anyone help?
