I have installed LE on a HP DC7600 which has a Radeon 5450 graphics card fitted. The PC is connected to the TV via the HDMI output. Video output is fine, however the audio only comes from the PC speaker and not through the TV. The audio settings are set to default. I have tried various different settings to no avail.
So my questions are:
1. Is this graphics card supported for audio output?
2. Do I need to reboot after changing settings?
