No sound on PBP default installation

[ivek]

Hi,

I just received the PBP with preinstalled Debian + Mate. everything is more or less fine, except that the sound doesn't work at all:
 - neither on speakers, nor on headphones
 - in Alsamixer no setting helped me, when trying to set output to default, the Alsamixer aborts and I can't rerun it
 - I tried checking sound from "control panel", I think there is no connection to Pulseaudio (but Pulseaudio is installed)
 - when I play a song (no sound ofcourse), one setting in volume control says that there is no app playing the sounds, although it's playing.

I haven't tried to update anything, I don't know the commands.
I don't know if I need maybe to set that UART switch if set to off, but I need to open the laptop for that. (as in thread https://forum.pine64.org/showthread.php?tid=8231)
I haven't tried it on HDMI, I don't see that port, only UCB-C, if it is meant for HDMI, I have no adapter to try..

I am pretty much a noob in Linux, so any help with an elaborated answer (links to explanations like "how to install or try out a new OS") would be appreciated 

Hi ivek,
I received my PBP just yesterday, and also had no sound. Found that "output volume" was set to Mute (under Control Center - Sound Preferences). All good once unchecked. Note: the "test speakers" under hardware does not work.
Apologies if this was really obvious and you have already checked this setting.
Cheers Bruce.

I had the same problem,  there is another thread on this same subject,  Deebeez had a quick & easy fix.....
rather than repeat it I suggest looking at that other thread...
AND  check your audio with real sound like YouTube or something....  The 'Test speaker'  does not seem to work on this OS.

Thanks four your help guys, still no luck

@bruce, All settings in that sound are grayed out, maybe that's a clue
@bcnaz, We already tried turning on everything in Alsamixer, the sound output is set to the only device that could play... if I set it to "default", the Alsamixer aborts and can't be started again...

If nothing helps, I will buy a MicroSD card and try another OS
