One place to start is to use pavucontrol (install it if you don't have it) to check to what output your sound is sent. Under "Output Devices", the text next to the icon of a sound card should be something familiar (for me it is "Built-in Audio Analog Surround 4.0". There might be options to change ports, if you have multiple speaker configurations.

I installed from the debian-10.0.0-amd64-netinst.iso. I am getting sound through the headphone jack, but nothing through the speakers. 1 sink (s) available. I can play music via juk and run the pacmd command then the output shows as active, but still no sound. I am no expert on the sound, especially with pulse audio.

Code: Select all. GRUB_CMDLINE_LINUX_DEFAULT="quiet snd_hda_intel.dmic_detect=0". and applied changes by invoking /sbin/update-grub followed by a reboot, still no sound output device... dmesg shows that the new parameter is transmitted to the kernel, but seems to have no effect.
