Any working non-USB audio input card?

[webb]

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.

[webb]

Nice! I'll be looking forward to that day

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

[webb]

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.

[bmarkus]

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

[Paul_123]

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.

[webb]

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 whether he would be willing to backport.

[webb]

It looks like Audio Injector http://audioinjector.net/

has a driver in 4.4.y https://github.com/raspberrypi/linux/blob/rpi-4.4.y/sound/soc/bcm/audioinjector-pi-soundcard.c. 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:

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.
