Hi All

My previous message was too long, resending with main information and
renewed requests.

Thank you

 Hi All,

 I request Urgently for support in guiding me to configure audio on my laptop.

 When I bought this laptop, I installed Ubuntu 18 / LM and the
 sound/audio didn't work. That time it was about something with the
 driver not ready. Ubuntu 20.04 was about to be launched, it was
 suggested in this list and I also thought to install Ubuntu20 when it
 will be launched. It might solve the problem. It didn't.

 I installed Ubuntu 20.04, but the audio did not work.

 NOW, I refuse to believe that in Ubuntu 22.04 the audio driver will
not work !!!

 Camera working on low resolution 640x480. At higher resolution there
 are vertical lines.

 I really need my audio / mic along with HDMI to work.

 Earlier alsamixer would show the device as Intel Gemini Lake / HDMI PCH.

 If more information is needed, please let me know, but help me get
 audio working.

 Thanks

 Nittin
