Hi dunghnguyen,

i do not own such a DAC, so i'm unable to test.

- Have you enabled dtparam=i2c_arm=on?
- Please check the journal for errors
Code: Select all
journalctl

- Also check the log (debug data) for errors

Actually, I used this dac board as shared on previous post viewtopic.php?t=4044

So I guess the dtparam=i2c_arm=on is not meaning for my case or this is to activate for the i2c for LCD display? My dac board is only I2S pins (GND, LRCK, BCK, DAT).

Anyway, I am not at home now. So I think I will re-flash the mSD card then redo the steps as your instruction again.

Thanks for your kind concern.

Hi all,

sorry my fault.

The driver is not for the ES9018K2M but for SABRE9018Q2C.

Hi alvaron,

please try to set the bit depth to 24 or 32 bit.

This can be done by adding
format "*:24:*"
to your /etc/mpd.conf
Code: Select all
audio_output {
   name       "snd_rpi_hifiberry_dacplus"
   type       "alsa"
   device       "hw:1,0"
   auto_resample    "no"
   auto_format    "no"
   format      "*:24:*"
   enabled    "yes"
}


Do not reboot after changing the file, because Rune will reset this file to default values.
You have to restart MPD instead:
Code: Select all
systemctl restart mpd

Hi Frank
I changed MPD config as you said....and did not reboot just rebooted the mpd config file as instructed
when I go back to runeaudio and opened the MPD option I get a message that said that the mpd config file
has been changed do you want to go to the default or edit....I went to the edit and checked the mpd config and the
format "*:24:*" was there...
then hit the save but it just stay there. I reopened MPD menu again and the same message appears the mpd config has been changed etc...

Hi Frank
I have it working now......
I did not pull down the mpd menu
just went to the USB flac memory stick and it played 100 percent no.....white noise at all
I was wondering if Audiophonics from France sells the exact same DAC with the pi3 option
and worked for them...
I still have a question.....how do you get rid of that warning sign when you pull down the mpd menu?
and off topic.....I have been experiencing problem adjusting the official 7 inch back lilght...have been
looking at the forum but no direct post have been found about the subject
again Frank many thanks for all the help

Hi alvaron,

how do you get rid of that warning sign when you pull down the mpd menu?

- edit the file "/srv/http/db/redis_acards_details"
Find your DAC and add "card_option":"format\t\"*:24:*\""
Here an example for the snd_rpi_hifiberry_dac
Code: Select all
$redis->hSet('acards_details', 'snd_rpi_hifiberry_dac', '{"sysname":"snd_rpi_hifiberry_dac","extlabel":"HiFiBerry DAC (I²S)","hwplatformid":"01","type":"i2s"}');

to
Code: Select all
$redis->hSet('acards_details', 'snd_rpi_hifiberry_dac', '{"sysname":"snd_rpi_hifiberry_dac","extlabel":"HiFiBerry DAC (I²S)","card_option":"format\t\"*:24:*\"","hwplatformid":"01","type":"i2s"}');

edit: changed it to the correct DAC

- execute these commands:
redis-cli del acards
php /srv/http/db/redis_acards_details

- reboot

I have been experiencing problem adjusting the official 7 inch back lilght

The driver for the screen provides an interface through /sys/. To turn the screen on you can use the command:
Code: Select all
echo 0 > /sys/class/backlight/rpi_backlight/bl_power

and to turn it off:
Code: Select all
echo 1 > /sys/class/backlight/rpi_backlight/bl_power

the brightness can be adjusted using:
Code: Select all
echo n > /sys/class/backlight/rpi_backlight/brightness

where n is some value between 0 and 255.

only works on v1.1 LCD hardware
