hello again. got it all running on a new raspberry pi but have no sound. im running the lite version of raspbian so my guess is there is something i have to type in? please help

I'm assuming it's not fruitbox related, so try this link...

https://www.raspberrypi.org/documentati ... -config.md

Also you can check the master volume from the command line by typing alsamixer

Cheers
Mike

Mike, thank you very much. This worked great.

I'm having an issue with sound though. I've gone through numerous posts trying to figure out why I'm not getting sound from the 3.5 jack or HDMI, but no luck with Fruitbox on Raspbian Stretch Lite. When I couldn't get any the online solutions to work, I thought maybe the board was bad somehow, so I flashed another card with Raspbian Buster with Desktop and sound worked fine on both 3.5 and HDMI. Put the card with Fruitbox on it in another Pi that I know has working sound, but no sound there. Is there anything specific to Fruitbox for sound?
Hi,

Sounds like your hardware is ok, so it's going to be a setup problem.

First thing to check is that the default broadcom sound driver is loaded. In the /boot/config.txt file you need to have the following line somewhere...
Code: Select all
dtparam=audio=on
If not, you need to add it. Remember to edit it in superuser mode, i.e.
Code: Select all
sudo nano /boot/config.txt
Second thing to check is that your master volume isn't turned down. Run alsamixer from the command line and crank up the volume using the cursor 'up' keyboard key.

Third thing you could try is to see if the default ALSA sound device is recognised by the OS. Type aplay -l (that's the letter 'l') from the command line and see if it detects the ALSA PLAYBACK device (probably card 0).

If both the above look ok, then you can use aplay to play a wav file. Copy a .wav file onto your Pi and use the command aplay <your wav file>. If you don't hear anything, then it's a system issue, not a fruitbox issue. Let me know what happens and we'll have another think...

Cheers,
Mike

Doh! I feel like such an idiot. The master volume was turned down. Thanks again Mike. Next up is to build a cabinet for this to look like an old juke box.

Thanks again Mike. The alsamixer was the perfect solution. FYI to HiFiBerry Amp2 users, you probably want your max digital volume to be around 60%ish if you want to be able to have a conversation while the music plays. I can't wait to show you the finished project.

That's great.

Not sure if it's of any interest to you, but on GitHub I have a separate project called rotary_alsa_volume which you can run alongside fruitbox, and will let you control the alsamixer volume using a rotary encoder connected to two GPIO of your choice. This way you can have an old style knob you turn to change the volume.

Ok, this might have been answered before, but I didn't see when I searched...

Got the HiFiBerry Amp2 running after some code modifications. Boot fruitbox.... and the volume is LOUD. Like push the volume down button four or five times loud. Any cures for this?

Otherwise, my 79 year old father is very impressed with your program and says he's never heard the old stereo play Marty Robbins that well!

EDIT: Saw the answer. Forgive my poor searching capabilities. Question for Mike, did you ever make volume logarithmic?
Hi

Yes volume is now logarithmic. Regarding the volume, I presumed you used the initial volume setting in the skins config file? (SongVolume setting in the [sounds] section). It's worth noting that this just sets the initial volume, so the user can still crank it up using the volume buttons to its loudest, which may be to loud for you, and also since there are only ten volume steps you may not get a small enough volume change each time. One solution to this is to change the master volume range before you run fruitbox, by using the alsamixer command line utility. You only need to do this once as the setting is remembered even after power cycling. Just type alsamixer from a command prompt and use the up and down cursor keys on your keyboard to adjust the maximum volume. Then when you run fruitbox you will be able to change the volume from silent to this max volume you have set.

Cheers
Mike

Didi,

Check out this posting I made on how to set up the sound so it doesn't blast at max when you start Fruitbox.

Thx, Greyfeld
The problem was not Fruitbox, the problem was the sound setting in the raspberry. I switched to the USB Soundcard now, I had lying around here.
Greeting Didi

Hi,

Been working on my Fruitbox project a little bit at a time and having a lot of fun. Thanks Mike! Here's a couple things I've run into and solved that might help others.

Sound issues

I have a Raspberry Pi 3b with a Hifiberry Amp2 on top that is driving a pair of vintage Acoustic Research TSW-210 bookshelf speakers that I refoamed some years ago. Since I installed Fruitbox v1.03 a while back, the volume controls (+/-) and sound effects for things like page turn have lagged seconds behind the onscreen video trigger. Installing version 1.11 solved that issue. Glad you found that fix.

I also had an issue where the sound at default Fruitbox and alsamixer levels was so loud it was vibrating the floor and my wife complained. LOL. Had to get that figured out. The symptom was that it started out blasting, but using volume controls (+/-) took forever to get the sound down to an acceptable level.

The key was getting into alsamixer on the Pi and setting the playback volume to 85% (experiment to find what's best for your application). There is a great step-by-step tutorial on how to set it to your desired level by SC Phillips on his blog here - http://blog.scphillips.com/posts/2013/0 ... with-alsa/.

It requires some command line work, but it is all shown clearly on his site. Great guide. Remember to save your alsamixer setting by doing a "sudo alsactl store" or alternatively reboot with "sudo shutdown -r now". If you just unplug the Pi, you will not get the setting saved.

Once you've done that, you need to go into your skin's fruitbox.cfg file and add the SongVolume parameter in the Sounds section using a text editor like vi. I set it to 50 which starts it at 50% of what you set the Pi's master volume at using alsamixer. That way you have room to move the volume up or down quite a ways. You might also want to turn the others down or set to 0. PageMove is really annoying to hear every so many seconds throughout a song, so I set it to 0.

[sounds]
InsertCoin Volume (0..100), Filename of sound effect when a coin is inserted (wav, flac, ogg)
LoadSong Volume (0..100), Filename of sound effect when a song is loading (wav, flac, ogg)
UnloadSong Volume (0..100), Filename of sound effect when a song is unloading (wav, flac, ogg)
PageMove Volume (0..100), Filename of sound effect when pages are moving (wav, flac, ogg)
SongVolume Initial song volume (0..100)

My settings:

InsertCoin = 30
LoadSong = 30
Unload Song= 30
PageMove = 0
Songvolume=50

Now that I have those issues resolved the sound comes on and I'm not blasted into the wall behind me. I have control of the volume quickly since the Fruitbox 1.11 version fix and I have some room to work with if I still want to crank it when the wife is not home.

One issue I've noticed is that I'm getting the thermometer symbol in the upper right corner after I use it for a while. The Amp2 apparently generates a lot of heat. I'm looking to put it into a portable container of some sort and it appears a fan will be needed to cool it. Anyone have any thoughts about that?

Next up is a touchscreen. I'm planning to get the Raspberry Pi Element 7" and see how that works. If anyone has any helpful advice on setting up the touchscreen beyond what's been posted to date, please respond with some tips.

Thanks Mike, great stuff and appreciate your engagement with us.
