Sound problems in Unity - input but no output
- by ana
I am new to Ubuntu, having just installed it for the first time on my Lenovo Thinkpad.
Since I installed it I have no sound output whatsoever. However, I can see from the graphical interface in Sound Preferences Input that the sound input appears to be working correctly.
I have tried the following:

https://wiki.ubuntu.com/Audio/InstallingLinuxAlsaDriverModules
ubuntu-bug audio
I have two sound cards,
cat card0/codec* | grep Codec
Codec: Conexant CX20585
Codec: Conexant ID 2c06
cat card1/codec* | grep Codec
Codec: Nvidia GPU 0b HDMI/DP
Codec: Nvidia GPU 0b HDMI/DP
Codec: Nvidia GPU 0b HDMI/DP
Codec: Nvidia GPU 0b HDMI/DP
And now have pretty much run out of ideas. Can anybody help?
