    Lost my speakers after update to 20.10

    Soundbar attached with Digital to tv that is attached to laptop with HDMI. Can't see the speakers in Pulse anymore. Re-installed Pulse and alsa. In Pulse configuration it shows "(unplugged)(unavailable)" for Digital Stereo

    Try rebooting the sound bar with it connected. Once it is started run:
    Code:
    dmesg | tail
    Do you see anything about sound?

    How do I check if it's a driver issue?

    Your set up is intricate with laptop speaker, TV speakers, soundbar, headset etc.
    Also, you did not mention which speakers have been lost?
    Did you have sound before updating to 20.10?

    In this situation, why not go back to basics?

    Unplug everything that is attached to your laptop.
    Do you have sound from the laptop speakers?

    if you have sound, plug in your next important device and test - trial and error is the answer.

    If not, boot up a live session with Ubuntu 20.04 and check sound?

    I lost the soundbar after updating from 20.04. I have unplugged soundbar and restarted it. I have sound from laptop speakers and headphones.

    Restoring back to 20.04 from Timeshift worked
