How to setup and test

[Denny9167]

Any suggestions on setting it up on Ubuntu Mate, there seems to be more settings in the boot/config.txt device tree, than found in Raspbian. Thanks

[flatmax]

Can you point me to the ubuntu mate linux repo online ?

thanks

I believe it’s 16.0, apologies should have posted that

[Denny9167]

I did a setup in Raspbian and it seemed to install correctly, but I wasn’t happy with the OS it was a little slow,and just didn’t like the interface. I looked into Ubuntu and found The MATE desktop and it looked like it would something to try, and after I installed it and played with it for a few hours, realized how much more this offered in the way of apps and ease of upgrading, and believe it or not responded faster than the Raspbian did, BTW I’m using and RPi 3 model B.

Can I install this audio card on a "headless" Raspberry Pi Zero W. I do not use the monitor with my device at all, just network SSH login...

Thanks!
Jesse

Edit: Nevermind, just saw this on the original post:

Manual setup method
Ensure you have the latest kernel : sudo rpi-update
Make sure the default audio device tree is not loaded for PWM output (/boot/config.txt), this is because it uses the same I2S bus. (Comment out dtparam=audio=on)
Make sure the Audio Injector device tree is loaded at boot time : dtoverlay=audioinjector-wm8731-audio
Reboot to force the correct device tree to load.

Then I also had to run:
alsactl --file asound.state.RCA.thru.test restore

Which contained:

Code: Select all

Thank you to who ever made this card! What an awesome and valuable audio platform!

Now I just need to figure out why my audio app which ran fine on the armv7 Pi does not work properly on this armv6 Pi Zero!

I keep forgetting its such a lower end and older processor arch.... Lacks NEON even!

[joe_h]

I have seen a few posts in this thread on people having the soundcard wired up properly, but the sound still playing through the hdmi on the raspberry pi. Was there a fix to this?

I have a brand new raspberry pi3 and just bought the stereo soundcard off of Amazon. I did the automated setup and everything is showing correctly in the config.txt and when I do a aplay -l. However, no sound comes out of the soundcard and all comes through the hdmi.

Below is everything you asked from others to post. Also, I tried the sudo alsactl store command for saving my alsamixer settings, but every time I go back in there the capture option is turned off.

Any help would be greatly appreaciated.

Code: Select all

# Enable audio (loads snd_bcm2835)
#dtparam=audio=on

# NOOBS Auto-generated Settings:
hdmi_force_hotplug=1
# enable the AudioInjector.net sound card
	dtoverlay=audioinjector-wm8731-audio

Code: Select all

[joe_h]

I just entered a detailed post, but I do not see it on the forum.

In brief it showed everything you have been asking others with the config.txt, the aplay-l and the alsamixer settings correct, minus the capture setting. As I mentioned it kept turning off on me and I couldn't get the sudo alsactl store command to actually save anything.

I am getting audio through the hdmi on the raspberry pi but not the stereo card.

Any help would be greatly appreaciated

Hi there,

Interesting problem !
The thing is that ALSA is saying that you have only one sound device installed - the Audio Injector sound card. It seems a little strange that it is playing through HDMI.

Have you tried removing any non-necessary HDMI lines from the boot.txt file ?

Hello

I know that this is not the real place for asking it in this forum i am sorry, but i dont see it anymore at the moment. Maybe someone can help me::

I stuck in installing the deb file. I use debtap on archlinux to convert it into AUR package.

when I use

>> debtap audio.injector.scripst_0.1-all.deb

i get:
>> xz: audio.injector.scripts-0.1-1-any.pkg.tar: Cannot allocate memory
>> mv: cannot stat '*.xz': No such file or directory

is there an alternative to install it on Arch-linux? Or any further advices?

Thx in advance.

Hello

maybe somone can help me or give me an advice:

i want to install a .deb package (audio.injector.scripts_0.1-1_all.deb) using

debtap

but it seems that there is a problem when debtap is creating the pkg.tar out of the .deb file:

input:

Code: Select all

root@alarm>> debtap audio.injector.scripts_0.1-1_all.deb
root@alarm>> 

output:
