Public bug reported:
The built in speakers and mic on my 2026 LG Gram (15Z95U-H.AU87U1, Ryzen
AI 7 450) do not appear to be recognized by a fresh install of Ubuntu
26.04. Output device shows as Dummy Audio, input shows No Input Devices.
The 3.5mm combo audio jack also does not work or show up as an
input/output option, even with a headset connected to it.
The HDMI port audio seems to be detected correctly, though I have not
tried sending audio through it. Bluetooth audio works as expected.
