Tried other answers in some other posts, but I can't seem to get it to work. image of alsamixer There's an image of what alsamixer looks like when I open it. Basically, I can't hear anything unless it's really loud in which it omes out EXTREMELY quiet. Tried restarting and everything. Please help, I'm a newbie here and this problem's been around for days, and I would EXTREMELY appreciate it if someone would give me answers. Thanks!
UPDATE: It looks like I need to switch my default card. Here's what it looks like when I type aplay:
$ aplay -l: **** List of PLAYBACK Hardware Devices **** card 0: HDMI [HDA ATI HDMI], device 3: HDMI 0 [HDMI 0] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: HDMI [HDA ATI HDMI], device 7: HDMI 1 [HDMI 1] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: Generic [HD-Audio Generic], device 0: ALC892 Analog [ALC892 Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: Generic [HD-Audio Generic], device 1: ALC892 Digital [ALC892 Digital] Subdevices: 1/1 Subdevice #0: subdevice #0 How do I make the ALC892 Digital my default, if that's the one I need?
UPDATE NO 2: Thanks to everyone, I was able to fix the problem. However, the sound coming out of the headphones is really quiet, to the point where you have to max out the volume slider to barely hear loud music. Help on this would be REALLY APPRECIATED!!!

Install PulseAudio Volume Control from Ubuntu Software Center.
After installing, in application's "Output Devices" choose default card by pressing green button next to it and it will always remain as default (device which is not selected is default, not the opposite). Do the same in "Input devices" tab if needed for you microphone.
You can also choose suitable profile in "Configuration" tab.
This great app also allows you to choose default card and other settings per application in "Playback" and "Recording" tabs (then specific application is running the options appear).
