I have installed on my son's new laptop SONY Vaio laptop SVF142C29M (instead of Windows 8) and we are very pleased. Congratulations to all who develop this excellent OS.My son loves it!

However, there is a problem with audio support on this machine. Playback works via the headphone socket, but not via the internal speakers. It's easy to work around this. But the microphone is not supported and this represents a serious drawback.

I am a LINUX neophyte. I have been as sophisticated as trying "sudo also force-reload" in the terminal. But that's about as sophisticated as I can get!

Any help would be appreciated or advice on whether I should log this as a bug and wait for a later release to resolve this.

Best wishes,

Richard

I've installed Kubuntu 12.04 for a friend on this computer and the speaker works correctly. Perhaps it's because I've installed a 3.11 kernel via:

apt-get install linux-generic-lts-saucy

And I had to also install bcmwl-kernel-source for the BCM43142 wireless. Also just for your information, when you have an issue with hardware, people will always you ask you for your Ubuntu version, kernel version, lscpi . Here is mine:
