After trying many things from different forums/help to get sound on my Dell Inspiron 6400 with Xubuntu 20.04, I still have sound issue:
In audio mixer is available only "output S/PDIF" but when on 'Configuration' Tab I select "Stereo Analog Output (unplugged) (unavailable)" : the sound is ok.
But when I restart, default is still "output S/PDIF" and no sound.
My audio card is detected and is : 82801H (ICH8 Family) STAC9200 options snd-hda-intel model=dell-m21 I modified the file alsa-base.conf but still not ok... Try to reload ALSA and PULSE, to re-install, ALSAMIXER not mute...all classical solution exposed.
My goal is just to have sound at startup without the need to change configuration in audio mixer...any idea ? Thanks for you help !!
