HI, it seems that in your alsamixer output the master canal is disabled:

open alsamixer and let me know how is the first controller you find [master]. My is:

This is what I find. Please read my p.s.

p.s. I find something interesting:

In the PulseAudio Volume Control, if I set Configuration to "Analog Stereo Input" first, then I can record, but cannot playback unless I reset to "Analog Stereo Duplex". Same thing with Skype. If I do nothing, the mic does not work at all, but if I set to Analog Stereo Input first, then I can talk but not hear the answer until I reset to Analog Stereo Duplex. Once I have done that then the rest of the conversation is duplex, and I don't need to set anything again. If I close Skype and reopen sometime later then I have to repeat the same process.

hi, your problem it seem to be a bug. I think it is: #728034

Revision history for this message
Fred Lam (deusnonest) said : 		#5

thank you. does that means that the natty upgrade solves the bug? I have got round the problem but it is a nuisance to have to set and reset the audio duplex function every time.

Can you help with this problem?

Provide an answer of your own, or ask Fred Lam for more information if necessary.
