The sound system is muted: 'Simple mixer control 'Master',0'. Use alsamixer to unmute and increase volume to 100 (if not installed use sudo apt-get install alsamixer command in a terminal and then type alsamixer and use your arrow keys to move through controls and increase volume and M key to unmute if MM is present under control bar.
Also you can go to System --> Preferences --> Sound and on Hardware tab and change the Profile (should be Analog Stereo Duplex or you can try something similar). In Output tab you can chose a device for sound output (if more than one option) and the Connector.

Good luck.

I have sound on vieo player, audio player even system sound works just fine, the only problem is the tvtunner which has no sound. For viewing i am using tvtime. The tvtuner is connected to sound card thru sound card "line in" wich is not muted (i tried the line in with an mp3 player to be sure ). I have dual boot win xp and ubuntu and on win xp i have sound so this is not a hardware related problem. I used ubuntu 9.10 beta which camed with a kernel earlier the 2.6.30 and the sound on my tvtuner worked fine. After upgrading to final version which uses 2.6.31.14 generic kernel version the sound on my tvtuner stoped working. My tvtuner is an Acorp Y878 which has an lg based tuner in combination with BT878 chipset.

The capture is set to line in in alsamixer? I presume you do, but I need you need to confirm. Then edit /etc/modprobe.d/bttv and set card and tuner to your tvcard. Another thing if you have radio on tvcard add radio=1. Here is a list of cards: http://www.zonap2p.com/showpost.php?p=52674&postcount=4that

I am not sure if the capture is set to line in alsamixer, i will post later.
i founded this http://patchwork.kernel.org/patch/29660/

I founded that the problem for my Acorp y878 tv tuner can be resolved by installing alsa 1.0.21 from proposed repository.
