Then in the linux, run 'sudo sh -c 'echo 1 > /sys/module/snd_hda_codec/parameters/dump_coef', and run 'alsa-info --no-upload' to get the alsa-info.txt. Please upload both generated log files. thx. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1918458 Title: [Swift SF515-51T, Realtek ALC256, Grey Speaker, Internal] Playback problem, no sound from speakers, headphones ok To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1918458/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
