I've pushed a commit to linux tree (and rpi-update kernel is rebuilt). Can you test? |
|
I have executed: sudo rpi-update from the terminal and the sound seems to be restored (after a reboot). There is still an issue with the quality of the Front Left and Front Right responses to the sound test buttons but the lack of sound seems to have been solved. Thanks you for your efforts. |
|
I have also tested the playback of sound under Rasbian Jesse after updating to 4.4.9-v7+. |
|
I just installed and updated Ubuntu Mate at 1.16.2 on my Pi 3B. I have no sound. I checked, and the confit.txt is the same as Daves. I need sound, and I want it to come out of the 1/8th audio jack. I use it without a monitor. The Sound Preferences has no hardware listed. Output has Dummy Output. |
|
What value does |
|
It came back numid=3,iface=MIXER,name='PCM Playerbakc Route' values=0. I'll set it to 1. Try that. |
|
It's confusing, but numid is the number of the control - it's the "values = " output that matters. |
|
Yeah, I still hear nothing. Output 0.00db, Dummy Output. I'm on the latest firmware too. The audio works if I plug in a monitor. |
|
What does |
|
Sorry, I gave up. I'm going back to Raspian. Ubuntu is not ready for prime time in Pi. After updating the firmware, Chromium does not work anymore. Firefox stopped working after I updated the system after a fresh install. It is just too unstable. |

@pelwell Your post solved it for me basically. I typed alsamixer and got this screen with the obvious problem. As you can see the dB gain is set to -102.38 by default. With Come to think of it, I had some issues updating my children's PIPER computer earlier this year, where the same problem ensued. That community is not as savvy as the usual linux user, thus they were having serious issues with their updates, which updated the firmware and caused this problem on their modified Raspbian OS. I am enjoying some music right now, as soon as I am done, I will reboot and confirm if it came back. |

OK.. Found this: Fix alsa configuration for future reboots When you exit alsamixer, run this command:

Since updating to the latest rpi firmware, there was no response to the Test Speakers buttons in the Sound panel, neither were there any clicks from the speakers when shutting down. All sound appeared to be muted. I tested this using different Raspberry Pi boards and HDMI monitors (with speakers) and the problem appeared to be due to accepting the update dated 30 April (kernel:snd-bcm2835 etc.)
I performed an rpi-update 384626a using the commit code from the previous update (dated 27 April) and my sound system returned to normal.
There is still a problem with the sound system in that the Test Speakers responses (Front Left and Front Right) are broken and incomplete but it is possible for the system to reproduce continuous unbroken sound when playing YouTube videos via Firefox.
If I am to continue to try out other firmware updates as they become available, I would appreciate advice as to how to blacklist the rogue update otherwise I am stuck with the update on 27 April.
