It sounds like your hard drive has bad sectors. Put that error message into
Google <Linux> and read some of the results.
The commands I gave you have absolutely nothing to do with this message. It was issued because the program "fsck" (filesystem checker) was automatically run when you rebooted, and it found inconsistencies in data on your disk(s).
For the sound issues, did you continue to boot and do you have sound?
For the bad hard drive, what filesystem(s) are you running?
There are two (at least) ways to check your filesystem(s). With a Linux distribution, you can use the one appropriate to your filesystem(s). In a terminal issue "man fsck" and read to find out more.
If you know the manufacturer of your hard drive, you can get a utility from their site which will check your drive; and if it's in warranty, will usually issue you a RMA number and instructions if it finds bad sectors on the disk. These utilites typically come in floppy and/or CD .iso image files. You download them and prepare the appropriate medium, then boot your computer with it and follow the onscreen instructions.
If you need more help checking your disk(s), post back the make and model; or the output of "df -h" and "fdisk -l" for our perusal.
