Please update your drivers, as outlined here: https://wiki.ubuntu.com/Audio/InstallingLinuxAlsaDriverModules. Please report back as to whether this fixes your sisue.

Luke,

It doesn't fix the issue. I just tried.

[Daniel González Gasull (gasull)]

Luke,

My apologies. It actually does fix the problem. But after updating the drivers I need to change the connector in System -> Preferences -> Sound -> input -> Connector. The new drivers show 2 connectors there: Microphone 1 and Microphone 2. While the old drivers shown only one microphone. Choosing Microphone 2 did the trick.

Thank you for your help. I hope these directions will help someone else.

[Luke Yelavich (themuso)]

Thanks for the feedback.

It's broken again. Now I can find only one microphone in System -> Preferences -> Sound -> input -> Connector. I am without sound.

[Daniel González Gasull (gasull)]

I meant I am without microphone.

[Luke Yelavich (themuso)]

Did you install any updates prior to the microphone functionality breaking again? If so, did you happen to also install a new kernel?

[Daniel González Gasull (gasull)]

Hi Luke.

Yes, I installed updates. I install any updates that the Update Manager tells me to. And as far as I remember, I updated the kernel.

Any logs I should look at?

Thank you.

[Daniel González Gasull (gasull)]

I still have this issue. Why is this marked as fixed when it isn't?

[Daniel González Gasull (gasull)]

I think some automatic update made my machine install some other drivers from backports.

I installed the ALSA drivers as explained in comment 2 by Luke above and it's working again (using Microphone 2 in the Sound options for input).

I don't know if this is an inconsistent state and I will stop working in a few days. Maybe then I'll have a better idea of the automatic update that is messing with this.

Further to comment #11, closing now as fixed.
