Well, while doing a few dozen hours of backups and other “essential uninterestings” including putting clones of my (now several) Raspberry Pi chips onto a backup disk, I made a clone of Raspbian Jessie (the newer release) onto an 8 GB card. Why? To make sure the backup, restore cycle worked end to end…
Just now, fooling around with it, I still had no sound. I had thought this would be fixed by this release…
So I did what all good folks do prior to taking on a chunk of work… I looked for “prior art”. And found it.
It looked very similar to what had been suggested for Wheezy (prior release that I never could get to have working sound), but I tried it anyway. This time it worked!
Here’s the “magic sauce”.
First off, the test case. I was at Iceagenow.info and they had a video of an airplane on snow. “Cutting a donut”.
Now you just know an airplane with a prop makes some noise…
Then the place with the magic sauce:
This guy had ported his own “Jessie” release prior to the formal one, so clearly “has clue”. Along with a lot of other tech talk, he has this from a comment down below, so clearly his ‘followers’ have clue as well:
Comment by Anders — Wed Mar 11 22:04:43 2015 to get sound There are some things still missing in this image. First you need the alsa-utils: apt-get install alsa-utils Configure the output to go to 3,5mm jack: amixer cset numid=3 1 Than load modprobe: modprobe snd_bcm2835 If all is done you should have sound on 3,5mm jack. If you want sound on hdmi outut: amixer cset numid=3 2 This modprobe and others should be loaded already at boot. Configuration should be possible at ./etc/modprobe.d Maybe one can refer to the already existing settings at Rasbian.
For me, alsa was already installed:
root@Ra2PiM2_8:/home/pi# apt-get install alsa-utils Reading package lists... Done Building dependency tree Reading state information... Done alsa-utils is already the newest version. 0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
That means I really only needed to load the module and direct the sound where I wanted it.
Oh, and my monitor doesn’t seem to like HDMI sound in, so I need to use the headphone jack (that works to headphones or the monitor).
Testing on a YouTube video (Blondie – Heart of Glass) had good sound. The video did pause a bit (just the video, sound was steady) as often happens on small processors; but is overall OK. IF I really want that all-in theatre mode experience, I’ll use a bigger box… but at least now I don’t have to change machines to to look at some modest res video of some guy at a blackboard…
Unfortunately, after that one song, I’ve had 200% CPU use by IceWeasel (so it’s using 2 cores) and still have not gotten another video to load and start playing. Even a simple one on rocket stoves… (i.e. not a lot of fancy fade and pan and stuff that drives compression nuts and chews CPU…)
Don’t know if there’s some “other issue” or if it is just a bit TOO much to be posting while playing videos… So a comment on that once this posting is up and I can test it “solo” in the browser.
I’m just really glad to have sound that works now. Any sound.
