What are the old and new hard drive model numbers and specs?
Correction: the 4TB drive is a Western Digital WD40EFPX. I was reading it by shining a flashlight through a gap in the frame and squinting from a wide angle because I didn't want to take the box apart yet again. I've trying several of the suggestions people have kindly posted here. The /etc directory on the new drive was getting messed up badly enough that I decided to try copying the 500GB drive's root partition to the 4TB drive using dd. The machine hung partway through the subsequent boot. So I wiped the root partition and re-installed Debian from scratch, leaving the /home partition intact. But the real magic was the re-installation of the Steam launcher. Since my Portal icons were on my desktop, and clicking them made it run (sort of), I was fooled into thinking everything was still there. But I found a detailed set of instructions for installing Steam at https://wiki.debian.org/Steam and followed them. This installed or overlaid the missing or broken parts and presto! my sound is now clean. Many thanks to everyone for your help. This a good lesson to not take too many things for granted, and also to be a bit more adventurous. (A full Debian re-install really doesn't take that long...) -- /~\ Charlie Gibbs | You can't save the earth \ / <cgibbs@kltpzyxm.invalid> | unless you're willing to X I'm really at ac.dekanfrus | make other people sacrifice. / \ if you read it the right way. | -- Dogbert the green consultant
