I've just installed Xubuntu 15.04 in my Dell laptop after using Ubuntu for over 2 years. I can't get the sound to work in my Samsung monitor, which is connected to the laptop through its HDMI port. It worked fine under Ubuntu and even during the live session with the Xubuntu CD, but it stopped working after I installed the OS and booted from the HDD.
Things I've already tried include:
- fully update my system through
- install PulseAudio Volume Control and change the output device (the HDMI port was not listed there);
speaker-testto activate HDMI sound (the HDMI sound output device is not listed, so it has no ID that I can use to call it);
- use a proprietary graphics card driver (the Software & Updates application suggested NVIDIA 340.76, but after I rebooted, I couldn't get video to work and had to reinstall the entire OS);
sudo alsa force-reload(nothing seemed to change).
Below is the relevant output for
lspci -v, showing my graphics card (the monitor is connected through HDMI after all) and
aplay -l, to show that the HDMI sound output device is not listed anywhere.
