![]() ![]() Regarding the question about updating the bios. I went onto the dell site to see if I could download a new driver for the Realtek ALC3254 but the only drivers that I could find on the site are only for Windows 10. In accordance with instructions given on this conversation threat, I ran "inxi -Fxz & arecord -l & dmesg | grep snd" the result was: Command 'inxi' not found, but can be installed with: sudo apt install inxi I still have "Dummy output" as the only sound output option. Pulseaudio -k & sudo alsa force-reload had no effect.īIOS -> disable audio -> boot to Ubuntu -> restart -> BIOS -> enable audio -> boot to Ubuntu did not work. Opened the terminal and ran sudo alsa force-reload. Opened the terminal and ran sudo apt-get install pavucontrol pavucontrol then entered configuration profile to set configuration to analog stereo out, only to find "dummy output" as the only option again. ![]() ![]() Ran tests with Dell technical support to confirm that the video and audio board and drivers are working, during boot up. I've disabled the secure boot, reinstalled plug audio, fed several different commands into the terminal, but it continues to not give any option for audio output aside from "dummy output".Īfter the mic and speaker output options disappeared in Configurations, leaving me with only "dummy output" as an option. Then, it stopped recognizing the audio board in a Dell G3 15 3590 ( service manual) ( audio specs). ![]() Things were working fine for the first three weeks on the new notebook. ![]()
