I have Ghost/MATE running well on a Dell Latitude 5510. One remaining issue is the speaker and microphone icons on the toolbar. The speaker icon is greyed out, but if I left click on either icon, I get a vertical grey bar with nothing showing. If I right click on either icon, I get a drop down with a selection for sound preferences. If I click on that, I can control the input and output from those tabs, but the hardware tab shows nothing. Some digging shows that this laptop uses the RealTek 236 chip for audio, that driver is installed, and I get sound out of Firefox and Strawberry. Is there some panel edit that I've missed? Thanks in advance.
