Odroid C2 + HiFi Shield+

mikebzh44 · October 29, 2016 at 4:57 PM

Hi.

Does latest alpha release supportHiFi Shield+ ?

Because I just try latest modified image for retroplayer :

retroplayer

and I can only choose for HDMI output, no optical output :

So do I have to mod the release (load module, enter command line, ...) to use optical output ?

Thanks.

Try

Code

modprobe snd-soc-pcm5102
modprobe snd-soc-odroid-dac

Then check the output of aplay

Code

aplay -l

Modules are not compiled or provided :

Code

LibreELEC-c2:~ # modprobe snd-soc-pcm5102
modprobe: FATAL: Module snd-soc-pcm5102 not found in directory /lib/modules/3.14.29
LibreELEC-c2:~ # modprobe snd-soc-odroid-dac
modprobe: FATAL: Module snd-soc-odroid-dac not found in directory /lib/modules/3.14.29
LibreELEC-c2:~ #

Do I need to install Volumio OS so I can copy modules into LE ?

ODROID Forum • View topic - C1+/C2 HiFi shield (pcm5102) driver

EDIT :

On Volumio, kernel is 3.4.79 and modules are :

Code

root@volumio:/# find . -name snd-soc-pcm5102*.*
./lib/modules/3.14.79/kernel/sound/soc/codecs/snd-soc-pcm5102.ko
./static/lib/modules/3.14.79/kernel/sound/soc/codecs/snd-soc-pcm5102.ko

./static/lib/modules/3.14.79/kernel/sound/soc/aml/m8/snd-soc-odroid-dac2.ko

I have try also with regular LibreELEC release :

LibreELEC-Odroid_C2.aarch64-7.90.007.img

But modules are not provided.

**lrusak** · October 31, 2016 at 8:07 AM Official Post

the modules aren't present because we don't have them in our linux-amlogic kernel. I'll see if I can port the driver and make a test build.

mikebzh44 · October 31, 2016 at 8:19 AM

Thanks a lot

The Odroid-C2 + HiFi shield will be the perfect substitute for my current HTPC (my AVR doesn't have HDMI input so I need to use optical).

**lrusak** · November 1, 2016 at 6:46 AM Official Post

please update to this build and then do again what I asked for

LibreELEC-Odroid_C2.aarch64-8.0-devel-20161031231959-r24348-g560ee96.tar

you might also have to put the following into /storage/.config/asound.conf, but try without it first

Code

pcm.!default  {
 type hw card 1
}
ctl.!default {
 type hw card 1
}

also, are you sure it is the hifi-shield+ or the hifi-shield2?

mikebzh44 · November 4, 2016 at 4:41 PM

Thank you very much for this build.

Modules are OK now :

And aplay find the card :

  Subdevices: 1/1
  Subdevice #0: subdevice #0

I have kill and restart Kodi but no optical output available on Kodi :

So I have create /storage/.conf/asoud.conf and restart Odroid C2. But I have to reload modules (where/how can I specifie to LE to load this modules at boot time ?).

But Kodi audio output is not displaying Optical output

Oops, didn't see this question. I will have a look this evening.

BTW, I will also try this tuto :

en:c2_hifi_shield [Odroid Wiki]

To load modules at boot time.

mikebzh44 · November 16, 2016 at 6:22 PM

It's a HiFi-Shield+

I try to load modules at boot time following tuto given in my previous message but :

/etc/modules does not exist

there is only /etc/modules-load.d/README

Quote

Name

modules-load.d — Configure kernel modules to load at boot

Synopsis

/etc/modules-load.d/*.conf

/run/modules-load.d/*.conf

/usr/lib/modules-load.d/*.conf

Description

systemd-modules-load.service(8) reads files from the above directories which contain kernel modules to load during boot in a static list. Each configuration file is named in the style of /etc/modules-load.d/program.conf. Note that it is usually a better idea to rely on the automatic module loading by PCI IDs, USB IDs, DMI IDs or similar triggers encoded in the kernel modules themselves instead of static configuration like this. In fact, most modern kernel modules are prepared for automatic loading already.
Configuration Format

The configuration files should simply contain a list of kernel module names to load, separated by newlines. Empty lines and lines whose first non-whitespace character is # or ; are ignored.

Each configuration file shall be named in the style of program.conf. Files in /etc/ override files with the same name in /usr/lib/ and /run/. Files in /run/ override files with the same name in /usr/lib/. Packages should install their configuration files in /usr/lib/, files in /etc/ are reserved for the local administrator, who may use this logic to override the configuration files installed from vendor packages.

If the administrator wants to disable a configuration file supplied by the vendor the recommended way is to place a symlink to /dev/null in /etc/modules-load.d/ bearing the same filename.
Example

Example 1. /etc/modules-load.d/virtio-net.conf example:

# Load virtio-net.ko at boot
virtio-net

See Also

systemd(1), systemd-modules-load.service(8), systemd-delta(1), modprobe(8)

Try to add snd-soc-pcm5102.conf in /usr/lib/modules-load.d but it's a read-only filesystem :

Code

LibreELEC-c2:/usr/lib/modules-load.d # touch snd-soc-pcm5102.conf
touch: snd-soc-pcm5102.conf: Read-only file system

So how can I load modules at boot time ?

Thanks.

**lrusak** · November 16, 2016 at 6:36 PM Official Post

/storage/.config/modules-load.d/

mikebzh44 · November 16, 2016 at 6:46 PM

Try :

Code

# systemctl stop kodi
# modprobe snd-soc-pcm5102
# modprobe snd-soc-odroid-dac
# aplay -l

  Subdevice #0: subdevice #0
# systemctl start kodi

But can find any SPDIF output in audio settings

Do I need to edit some files in /storage/.conf ?

Try to modify /storage/.config/modprobe.d/disable-spdif-for-hd-audio.conf but modules are not loaded at boot time.

But still not SPDIF output in Kodi :

**lrusak** · November 16, 2016 at 7:06 PM Official Post

can you try using SPDIF with that alsa device? just to make sure that that doesn't work.

mikebzh44 · November 16, 2016 at 7:12 PM

Will try this next time, just unplug all the stuff because each time I want to test Odroid C2, I need to unplug my HTPC.

Hi, I'm in the same case : Odroid C2 + HiFi Shield+

I'm trying to get the sound to the DAC, because my amplifier is connected to RCA.

Here's are the step I made, after upgrading to the version http://lrusak.libreelec.tv/LibreELEC-Odr...60ee96.tar

I also made a file /storage/.config/asound.conf with

Code

pcm.!default  {
 type hw card 1
}
ctl.!default {
 type hw card 1
}

Still, I cannot find the DAC audio output in Kodi settings and the sound still comes out of the TV speakers (through HDMI)...
If it appears righit with aplay -l, why doesn't it show on the UI ?

Am I missing something ?

Thanks for everything

Anyone ?

Why can't the Odroid HiFi DAC be recognized ?

Because it's not supported in our kernel yet?

**chewitt** · November 27, 2016 at 7:50 AM Official Post

Random thoughts following the investigation of some weekend investigation fo Raspberry Pi DAC cards:

a) Some devices need IEC958 to be declared properly .. see here:

snd_slice: add 16-bit support and initial IEC958 conf · chewitt/LibreELEC.tv@9d91337 · GitHub

b) If you have "Sync Playback to Display" enabled in Krypton builds everything will be resampled to 2.0 PCM

Aplay outputs this :

Code

**** List of PLAYBACK Hardware Devices ****
card 0: AMLM8AUDIO [AML-M8AUDIO], device 0: I2S.31 dit-hifi-0
  Subdevices: 0/1

card 1: ODROIDDAC [ODROID-DAC], device 0: I2S.31 pcm5102-0
  Subdevices: 1/1
  Subdevice #0: subdevice #0

Doesn't that mean that the DAC audio output should be available in Kodi ?
