    No Audio

    I have 18.04 on a Lenovo Thinkpad 11e. I was having problems with no audio coming from websites such as youtube. On the other hand if I went to Sound Settings to test the speakers I would get the audio out. So I started playing a bit with alsamixer and pavucontrol with no luck. Furthermore, now after that exercise, there is no audio at all, not even in the Sound Settings->Test Speakers. Even the volume control on the top panel disappeared (I'm using Gnome flashback). I followed some recommendations such as:

    sudo apt remove --purge alsa-base pulseaudio
    sudo apt install alsa-base pulseaudio
    sudo alsa force-reload

    to no avail.

    I will appreciate any help.

    First glance at 'system settings' to know if the hardware is well identified; then also see warnings/errors from 'journalctl -b' about hardware/alsa/sound
    Did that trouble came after an upgrade ?

    The trouble came after playing with pavucontrol because I wasn't getting sound from websites such as youtube - as I said in my posting, the speaker test was working but now it is not and I don't even have the volume control anymore on the top panel.

    Re: No Audio

    what is the hardware - the sound chip?

    what happens if you try
    Code:
    sudo alsa reload -c
    Read the easy to understand, lots of pics Ubuntu manual.
    Do i need antivirus/firewall in linux?
    Full disk backup (newer kernel -> suitable for newer PC): Clonezilla
    User friendly full disk backup: Rescuezilla
