Wolfson drivers not in next Raspbian update

It is supported in the new release of XBMC Gotham Cheers!

Hi Paul Garcia

I have same problem

So

I need your help

Would you tell me how to setup XBMC Gotham?

Can I install raspbmc-2013-12-23.img first,and update the XBMC?

I search the XBMC

in this post

http://forum.xbmc.org/showthread.php?tid=176043&page=80

wget -O xbmc-14-20140420-nc3.tar.gz http://goo.gl/tNRTO0 --no-check-certificate

pv xbmc-14-20140420-nc3.tar.gz | tar xzf - -C /home/pi/.upgrade

sudo cp /home/pi/.upgrade/xbmc-14-20140420-nc3/{fixup_x.dat,start_x.elf} /boot

ln -sfn /home/pi/.upgrade/xbmc-14-20140420-nc3/xbmc-bcm /home/pi/.xbmc-current

sudo reboot

so

my step will working?

I contacted Wolfson HQ and received this response today. Hopefully they have some good news coming. I will post again once I receive and update.

 

Hi Todd

Thanks for your email. I have someone in HQ working on response, and we aim to have it to you tomorrow.

I wonder if the 'someone in HQ' is in Austin, Texas? Quite topical really, with Pfizer trying to take over Astrazeneca ...

My desired setup is XBMC -> Wolfson DAC -> vintage Harman-Kardon receiver.

You could try my experimental OpenELEC build:

http://www.horus.com/~hias/tmp/openelec-wolfson/

This is OpenELEC 4.0 with kernel 3.10.25 and the Wolfson driver plus the "use case" scripts and a few minor modifications so that the Wolfson card should work out of the box. I just uploaded a new build (20140514) based on the OpenELEC 4.0.1 release.

Please note:

This is an experimental build, although it works for me it could well have bugs.

Especially USB devices might be problematic due to the old kernel.

I don't think the Wolfson driver supports AC3 passthrough, maybe it does, but I can't test it - I'm using only an external stereo DAC.

so long,

Hias

Awesome, thank you so much!  I'll give it a try this evening and let you know how it works.

Best,

Ben

This seems very promising and projects upstream by end of June at the latest as that's the last day of Q2. Which should then allow all the Media Center Teams time to implement on their schedule which typically I don't think they sleep much. Hope this alleviates some of the stress and frustration anyone may be feeling. I hope to always give the benefit of the doubt with reputable companies that they hold true and won't release a statement like this unless they were 100% confident in it.

Hi Todd,

Thank you very much for contacting us with regards to the Wolfson audio card for the Raspberry Pi. We are glad to hear that you are a fan of the card and look forward to integrating within projects in the future.

With regards to the PR activity for the Raspberry Pi foundation our plans were to release the board with working software which we have now completed and in parallel work on up streaming the device drivers to the Raspberry Pi foundation. We are executing to this plan and will make our software available for up streaming in Q2 2014. I can confirm we are track to achieve this at present.

I hope you find the audio capability of the audio card exceeds your expectations, we have certainly found that it adds a completely new dimension to the audio possibilities of the Raspberry Pi. 

We would of course appreciate any feedback you would like to provide in advance of publishing your review for us to consider.

Best regards,

Wolfson team

Guys feel free to let me know. Direct Message here I prefer to support@raspians.com if you like please put Wolfson Audio Card (Whatever else) in the subject line and I'll start compiling and researching what is known vs what is yet to be revealed.

Put whatever as to what questions you may have as I can't test every single scenario or device. I'll put AC3 passthrough on the list. If you field other questions anywhere else or see other questions I would love the input.

I hope you are right. However we have been here before http://www.element14.com/community/message/107217/l/re-wolfson-modified-noobs-raspbian-zipped-img-cannot-unzip-new-download#107217

In that post Andy Laing (I think from Element14) said;

"We are currently working with the developers at Wolfson and the RPI Foundation to get the drivers uploaded into the official Raspbian Kernel.

This download image is only ever intended to be a temporary measure, and we will be removing this image as soon as the Wolfson drivers are embedded into the official Raspbian kernel. Once complete, you will only need to do an "apt-get upgrade" to download the kernel drivers for this audio card.

We are expecting this work to be completed within the coming weeks and I will update this thread again once this is completed and provide instructions on how to update your standard Raspbian builds to install the new drivers and additional software needed to run the Wolfson audio card."

That was posted by Andy Laing on March 24th. Note he said that they were expecting the work to be completed 'within the coming weeks'. You would have thought therefore that 6 or 7 weeks later we should not still be waiting for something to happen, and with no further word from Wolfson or Element14 (until you prodded them).

I'd take 'within the coming weeks' to mean 2 or 3 weeks, not 6 or 7. Or indeed probably more weeks yet to come. That sounds like 'months' to me.

Works great, and to top it all off, my USB WiFi dongle works out of the box (I had to compile a kernel module for it before).  Thanks!

I agree, this is ridiculous. I bought the card with the understanding that the drivers would be in the kernel within weeks. I am now still waiting.

Wolfson needs to get their act together

Worth the wait, WAC sound better than the hifiberry plus the internal class D amplifier drive loud speakers with no issue , gone thru all the testing, ready to set up my whole house audio.

I don't think anybody here thinks the Wolfson isn't a good product, it's just that the good work that has been done on it is being let down by poor support.

There's a few problems

1. The huge 4.4GB ZIP file which doesn't unzip with standard tools (does work with 7-zip) is based on NOOBS with Raspbian. It's running a 3.10.25 kernel with the modules added for the Wolfson support. It's running RPI firmware (/boot files) from January 6th. There's no easy way to update that without pulling the kernel source and building your own with the Wolfson modules included.
2. The software is based on Raspbian Wheezy, what happens when The Raspberry Pi Foundation move to Raspbian Jessie?
3. That 4.4GB ZIP file wouldn't fit on a brand new (£13 high spec Samsung 8GB card from Maplins). It needs to have NOOBS removed (to shrink it by 1.2GB) or it needs the Raspbian root filesystem squashed down by 500MB so it's guaranteed to fit any 8GB card. It's not difficult to extract the Raspbian extended partitions from a NOOBS card and move them back to primary partitions (but why should I have to do that).
4. Most hardware add-ons have an Raspbian DEB file that you download and add to your existing system. No special card, no special kernel needed. There must be a way to make the Wolfson kernel modules agnostic to the kernel version (within reason, it may need to be tied to a major version 3.10.? vs 3.12.?). I don't want to be forced to stick with a 3.10.25 kernel (what happens if the next Heartbleed exposure is in a kernel module, what happens if I get some other hardware that needs additional kernel support (albeit I'll have the same discussion with them)).

Well, the 4.4Gb download was supposed to be only a temporary solution, not a permanent one. Towards the end of March we were told that work was being done to get the Wolfson drivers included in the standard Raspian distribution 'in the next weeks'. However, we are still waiting for that. The drivers weren't included in the recent Raspian update. If the drivers are included in Raspian then presumably you can do a normal update. If the foundation moves to Jessie then a further update will be required (for the Wolfson driver).

It's not a satisfactory situation,and this is what we are complaining about. I don't know if we've ever had a comment from Wolfson in this forum, and certainly precious few from Element14.

Have you noticed that Ragnar Jensen has already produced a stripped-down version of the Wolfson download? A number of us are using that.

I am using Ragnar's RaspbianW version. That was a much less painful download on my slow ADSL line.

I'm thinking about building on my Raspbian Jessie (yes I'm running that early) with the 3.12.19+ kernel, but that's going to be a set it going at bedtime project.
