Hi Ubuntu Mate Pi users,
Thanks for any assistance. I’ve been running MATE Desktop environment 1.10.2 (img 15.10.3) on a Pi 3 for about two weeks (I’m pretty busy so haven’t had much time to problem solve) and have noticed there is no sound output whatsoever. I do not have the same issues with Raspbian and Openelec on the same device. Very puzzling.
I am a relative newcomer to Linux/ubuntu systems and can call up basic commands using terminal. I installed a bunch of ALSA Gui and sound control applications (such as PulseAudio Manager) on this installation of Ubuntu Mate but none of these applications offer me any ability to route the sound using different drivers for the Pi. I’m presuming the bcm2835 ALSA is the sound hardware the pi 3 uses should be recognized by Ubuntu to play sound from start up. There doesn’t seem to be a way to search for a more compatible driver or device. I also followed some instructions I already found on this forum for editing the HDMI config settings to boost sound and keep hotplug on, etc but this did not solve the problem.
So, just to clarify, I am getting no sound at all (system sounds, media playback, audio streams etc) when using Ubuntu MATE - from either HDMI AND audio jack. The system sound preferences shows playback occurring in input - but absolutely none of this comes out through headphones/amp/mixer at my end through either the HDMI or audio jack outputs from the Pi. This is even more strange as the sound works fine using boot images of Raspbian and OpenElec using the same Pi 3 - meaning, this is unlikely to be faulty hardware.
I’d also like to specify, I prefer my audio to output through the analog jack as I use several systems through a mixing desk in case anybody wants to help me configure sound on this little system.
Thanks in advance for any light you can shed on this issue I’m having.
Cheers!
