SPDIF not active in 4.7.3-sunxi

martin-by · October 16, 2016

Hello,

I have installed MPD & ALSA (pulseaudio is removed) on CUBIETRUCK.

Wtihin modules I added "sun4i_codec" & "sun4i_spdif" to get loaded.

With "aplay -l" I only get:

Do you have any hint to get SPDIF active?

Best regards,

zador.blood.stained · October 16, 2016

Some kernel options were missing. This will be fixed in a new release, meanwhile you can try installing this prebuilt kernel: https://www.dropbox.com/sh/ztxjghmrthjf8nc/AADvh1QuxF8nbsfMnXuBWylSa?dl=0

New card is detected on my Cubietruck, but I don't have any SPDIF receivers to test the playback.

Hello zador.blood.stained,

thank you for your quick response!!

I am still learning on Linux:

I have to install both .deb files using "dpkg -i" command, right?

Best regards,

Martin

zador.blood.stained · October 16, 2016

I have to install both .deb files using "dpkg -i" command, right?

Yes

martin-by · October 16, 2016

So, after installing --and a reboot-- both files all other devices are gone (wifi, Bluetooth, ..) and none soundcard is detected.

This is my actual lsmod:

realtek                        2775    0

Must be the /boot directory the same on mmcblk0p1 and my SSD (now my root directory)?

How to reset to old kernel?

Please remove any custom module names that you added from /etc/modules file recently. All sound and SPDIF modules are loaded automatically in any case.

Must be the /boot directory the same on mmcblk0p1 and my SSD (now my root directory)?

/boot directory should be on your SD card (/dev/mmcblk0p1) and it should be mounted to /boot during the upgrade. systemd-modules-load issue may be caused by incompatibility between kernel on boot partition (zImage on SD cards first partition) and installed modules. If you mount /boot directory and repeat kernel installation, this should be resolved.

Edit: you should add entry for /boot partition to fstab, otherwise any Armbian kernel upgrade will break your system. Did you move rootfs to SSD manually or did you use nand-sata-install script?

martin-by · October 16, 2016

I moved rootfs via dd command manually and changed the boot.cmd .

Should I change my boot.cmd back to boot from sdcard (?) and :

performing the upgrade to new kernel again
run the nand-sata-install script the to overwrite my SSD?

EDIT:

Or should I start with a fresh SDCARD installation?

zador.blood.stained · October 16, 2016

EDIT:

Or should I start with a fresh SDCARD installation?

This would be the easiest solution, especially if you dob't have too many custom settings and software in old installation.

Should I change my boot.cmd back to boot from sdcard (?) and :

performing the upgrade to new kernel again

run the nand-sata-install script the to overwrite my SSD?

This should work too

martin-by · October 16, 2016

Thank you for today!

Tomorrow I give a fresh installation a try.

martin-by · October 22, 2016

This would be the easiest solution, especially if you dob't have too many custom settings and software in old installation.

This should work too

Hello,

now all is running well (soundcard found, MPD plays over ALSA).

new sdcard image
apt update & upgrade
dpkg -i of new Kernel deb
setup of mpd, minidlna, webmin
mounting my HDD permanently to /mnt/HDD
installing my SSD via usb sata adapter
running nand-sata-install script

Thank you for this!!!!

Best Regards,

Martin

zador.blood.stained · February 21, 2017

I'm using 4.4.11 mainline with attached DTS and DTSI files.

Is something wrong?

https://linux-sunxi.org/Linux_mainlining_effort#Status_Matrix

SPDIF support for A20 appeared in mainline 4.7

Edit: Since you have sun4i_spdif in lsmod output you either mixed up your kernel version number or tried to backport SPDIF support to 4.4 LTS kernel. In the first case you need to check kernel config and dmesg for issues and missing options, in the second case we can only offer support for current Armbian kernel version.

February 21, 2017

Uuuups, sorry, my mistake. I'm using 4.9.11, sorry. It's pure mainline, without any patches or so.

I've compiled spdif, i2s, can, ... as modules.

But you had it running on mainline kernel before, or is this the first try? I mean, it could be broken.

February 21, 2017

I've reactivate my BPro after a long time...

What do you mean with "it could be broken"? Hardware? Kernel? DTS?

Some config options may be missing, especially if you didn't use Armbian config, i.e. CONFIG_SND_SIMPLE_CARD

Igor · February 21, 2017

I've reactivate my BPro after a long time...

What do you mean with "it could be broken"? Hardware? Kernel? DTS?

That SPDIF support in kernel was somehow broken, stopped working. I am trying to find out if you might have it working in v4.9.10 (or older) ... and it stopped working on upgrade to version released few days ago. In such case last known good kernel is a starting point.

February 21, 2017

@Igor: Ah, okay, I see. No, my last activities mit BPro were a couple of month ago...

@zador.blood.stained: Is there a list of modules which have to be activated to get SPDIF running?

I've checked my .config and indeed CONFIG_SND_SIMPLE_CARD is not activated. Or where I can download a config file from Armbian?

zador.blood.stained · February 21, 2017

@zador.blood.stained: Is there a list of modules which have to be activated to get SPDIF running?

No such list, but it should be working with the config provided by Armbian. If you decide to change/minimize it, we can't provide much support for this scenario.

February 21, 2017

Yes, I unterstand. There can I download the armbian config?

zador.blood.stained · February 21, 2017

There can I download the armbian config?

February 21, 2017

Many thanks!

I'll test this and give feedback

February 21, 2017

Hi guys,

SUCCESS!!!

After I enable CONFIG_SND_SIMPLE_CARD in my kernel config and recompile the stuff, I've got an error:

[    1.697960] OF: /sound/simple-audio-card,codec: could not get #sound-dai-cells for /spdif-out

during booting.

So, I added this line (bold) to DTS file:

spdif_out: spdif-out {
                #sound-dai-cells = <0>;
                compatible = "linux,spdif-dit";
        };

build a device tree blob and rebootet my BPro.
