Hello everyone,
I've had some minor experience with Linux before but never mastered commands or terminal usage, so please bear with me here...
I recently installed Bodhi 6.0.0 on my Acer Chromebook 15 CB3-532. According to the system, the sound is working (I had a bouncing bar indicating sound when I tried playing a YouTube video, but I have no sound through the speakers, headphone jack, or HDMI out (no video for HDMI out either, but that's another issue for another time).
Am I doing something wrong software wise or is this a hardware issue? I'm kind of wondering if I accidentally disconnected something when I opened up the bottom to remove the write protect screw.

Thank you for the response and the welcome!
Sadly, no joy in Mudville. I copy/pasted each command into terminal and then rebooted with no sound. I then tried hand typing the commands, same result. I did notice it threw up several error messages during the final "Force-reload" step, if that indicates a mistake on my part anywhere...

Did you try opening alsamixer in a terminal? Open Terminology (Bodhi Linux's default terminal emulator), type alsamixer and hit enter. This pulls up a sound mixer, alsamixer. The interface is a bit clunky to get used to, but easy to use with some practice. Check around for muted channels. Be sure to check if you can scroll left and right...I missed a "hidden" channel once and had a mysteriously muted machine due to not seeing this. Un-mute until you get sound. I'm not on my Bodhi system right now to walk you through exact directions...but hopefully this helps get you close. Also, check earlier posts in the thread that thewaiter posted, there is more related discussion. Oh, side note - be careful not to have headphones on while paying with this...you can inadvertently hit some serious dBs when you find the correct channel and un-mute it! Good luck and welcome to Bodhi Linux! |

I had tried the mixer at one point but didn't realize how many channels there are in there. I kept scrolling and nearly everything was muted. I kept going until everything was unmuted and somewhere along the line I heard the speakers crackle. That did it. Now to go thru and make sure everything isn't cranked to the max, LOL. Thanks so much everyone!

Unbelievable. I had it working last night and now there's no sound again. I've run through all the mixer settings and unmuted everything. At best I get a lot of hiss from the speakers, at worst a high pitched whine that makes my ears want to bleed.

I'm only guessing, but possibly too many channels are un-muted. I suspect there is something creating a feedback loop internally. Try eliminating mutes, doing them one by one. And then add them back possibly? I don't have a sound card on my current machine as its a Xeon server, so my alsamixer reveals nearly zero inputs/outputs to mute. I'm not sure if you use Discord, but someone there may be able to assist you in more real-time. Sorry it was working and then not...good news is you are close, I suspect!

Thanks Oblio. I hadn't thought about a feedback loop but it makes sense. I've had that issue with stereo equipment before.
It seems "SPOR Mix SpkVol R" & "SPOR Mix SpkVol L" might be the culprits as they start the squealing. Once it starts, the volume monitor won't even acknowledge anything VLC is playing. I had it playing this morning and once I unmuted those two channels the squeal began and the sound stopped even though VLC said it was playing.

Well, this can't be good... I swear I smell hot electronics, if you know what I mean. The speaker grills feel a bit warm and the left channel is completely dead.

 That doesn't sound great, I wonder it that circuit overloaded? Does the issue remain after powering the system down and giving it a few minutes? Sometimes amplifiers/protection circuits will kick out on overload, over-temperature, or if a fuse blows...not positive what circuitry (if any) exists within the Laptop/Chromebook. |

To be honest, I gave up. I had tried some other distros on the chromebook without success but I tried Solus Budgie last night and a few hiccups aside it seems to be working well and making the chromebook snappier than it was. Audio and HDMI out worked out of the box as well.
It seems the left speaker did take something of a hit as it's quieter than the right, but I will deal with it.

I let ya down, room503 - sorry I lead you astray. However, I'm glad you found something for your Chromebook. All the best. |
