Title: [Swift SF515-51T, Realtek ALC256, Grey Speaker, Internal] Playback problem, no sound from speakers, headphones ok Status in alsa-driver package in Ubuntu: Confirmed Bug description: Expect : sound from speaker Instead, obtain : no sound. Tried various configuration of /etc/modprobe.d/alsa-conf with : options snd-hda-intel model=XXXX and options snd-intel-dspcfg dsp_driver=3 or 1 and systematic reboot. Either I get dummy output, or I get proper output detection, alsamixer and pavucontrol seems 100% ok, but no sound comes from the speakers. I'm under a dualboot with Windows 10, BIOS fast boot disabled.
