Hi,

Half of these mails are hitting my spam filter, can be hard to keep up.

By way of an update on the audioinjector zero soundcard with streambox:

I was able to get the system fully up and running, using the onboard supplied electret. Sound quality was poor with significant wifi noise with the supplied electret. I've ordered some em172 capsules in the meantime. 

I think the significant noise on the signal was because the soundcard is not properly isolated from the pi zero w it was sitting on. wifi noise was only experienced when streaming audio to locusonus soundstream. So now i need to unsolder the soundcard, and mount using 40pin ribbon cable. 

In summary, altough I may get this audioinjector zero card working, having to install using a 40 pin ribbon cable to defeat wifi noise is not ideal. I'll report back here when I can verify that the board works OK with the ribbon cable. Not sure I can recommend this board TBH, defintely not noob friendly, wifi noise, mono mic only, etc. i know a bit of linux, so was able to muddle through.

ha! nice setup

maybe the primo capsule might like a bit more bias if it's an option (around 6V, I think), but seems like this is working well as is

Hello all,

I finally got my franken-board working! Currently running a test from the balcony of my parents house, but I’ll be moving it to the slagheap this week. 


I've attached two photos of the setup: I have a Wolfson Audio Card modified to fit the Pi A+ with a simple RC circuit providing the 3v needed to power a mono Em172 capsule.


Currently without a fluffy so the wind noise is quite apparent.

Hi Aidan, all,

I'm trying to make work a Audioinjector-ultra with streambox. I'm in contact with Stéphane.

At this point, it works with a regular Raspbian, but not with Streambox, which is on Arch. Probably a driver issue.

Fortunately a friend has a Focusrite to borrow me for Reveil.

We can share experience, feel free to write me private message.

hi folks,

Wondering has anyone looked at the audio-injector soundcards? I have a zero soundcard which I'm attempting to configure for a zero based streambox, Audio-Injector/stereo-and-zero. 


Thanks,

Aidan

Thanks Udo,

I'll try to have another look tomorrow - your config file could be very helpful if I get the Pi 2 up.
Very kind offer,

With kind regards,

Karina.

hi Karina,
I've a pi2 with cirrus, works fine. If you need some configs, let me
know.
