Title: Any working non-USB audio input card?
Post by: webb on February 10, 2017, 09:41:23 PM

Has anyone successfully set up a non-USB audio input card, e.g., Wolfson? If so, how?

Many thanks,
Webb

You can check the audio card drivers in the kernel, either kernel source, kernel config or alsa.modules-KERNEL.tcz.

Also you can check piCore based piCoreplayer for supported audio cards

Wolfsson used a messy dirty driver for an old Raspbian a while ago which was useless and was not supported in the official RPi kernel for long time. I have no idea whether it is change or not recently.

You can PM sbp one of the piCoreplayer authors here.

I just noticed that a new driver for the Wolfson card actually was merger into the official raspberry kernel a few days ago.

So when Bela build a new piCore based on the newest kernel, there should be official support for the Wolfson card.

Nice! I'll be looking forward to that day ;D

Maybe once. It is not in the current 4.4.48 used by Raspbian.

Looks like it's only in the rpi-4.9.y branch: https://github.com/raspberrypi/linux/pull/1810

They aren't spending much time on 4.4.y anymore.    All active rpi developement is in 4.9.y.  I'm a bit surprised 4.9.y is not already default.

True, since a long time no new RPi features, drivers, etc. appear in 4.4.y only following upstream.

Maybe it is the time to try 4.9 for piCore 9.0

I've been following that quite a bit Bela.  They keep breaking things quite a bit still.  Quite a few of the i2s soundcard drivers have only recently been fixed so they compile.

But 4.9 is definitely on the close horizon.

If the current plan for piCore 9.0 is 4.[4-8], I would be happy to ask the dude who made the 4.9 driver http://www.horus.com/~hias/cirrus-driver.html (http://www.horus.com/~hias/cirrus-driver.html) whether he would be willing to backport.

It looks like Audio Injector http://audioinjector.net/ (http://audioinjector.net/)
(https://images-na.ssl-images-amazon.com/images/I/91BwEPXAp7L._AC_UL115_.jpg)
has a driver in 4.4.y https://github.com/raspberrypi/linux/blob/rpi-4.4.y/sound/soc/bcm/audioinjector-pi-soundcard.c (https://github.com/raspberrypi/linux/search?utf8=%E2%9C%93&q=audioinjector-audio). I'll test it.

Hi there,

Has anyone managed to get the Wolfson audio card working in piCore?

I posted some info to another thread:

http://forum.tinycorelinux.net/index.php/topic,17546.30.html (http://forum.tinycorelinux.net/index.php/topic,17546.30.html)

Thanks,

Hi Petar,
As you probably know I got the card "working"  but it does not load the driver automagically from boot.
Still working on that.   I started a thread for that in this forum.
