    the audio doesn't work with chromebooks, or at least not the one i have. i've followed a couple different instructions from a couple different threads, either on here, or on places like askubuntu and the linuxmint forums.

    for context, i'm using a dell chromebook 11, codename candy

    i've run some commands

    ======================

    i've messed around with alsa mixer and at best got this

    card: chtma98090
    item: codec_out0 mix 0 codec_in0 --- this activates the speakers, but i still don't get audio

    ======================

    i've looked up the sound card itself, as it seems to be the only one that gets the speakers to work, n i found this forum

    https://forums.linuxmint.com/viewtopic.php?t=320117

    and following the instructions, i still got no audio.... but i did get a smell from my speakers... so.... uh.... help?

    (note, this is both for the live cd and the install, no audio at all. i have no idea what the issue is, and i don't want to explode my laptop over audio issues)
