hi,
i have installed rasplex (0.7.1) as one of the OSs in berryboot.
now my question is: i need to change rasplex config file to add hifyberry digi, how do i access (ssh into it would be fine) the file?

the config file i can see on the SD card looks like the config file for berryboot. if i try to add:
“dtoverlay=hifiberry-digi”
the hifiberry digiplus doesn’t show up in rasplex

thank you

I think @dlanor covered this in one of his excellent Berryboot How-To’s in this forum.

Just a thought, did you disable LIRC

thank you,
from dlanor post I do understand there is only one config file. so i have already added:
“dtoverlay=hifiberry-digi” to that file.

i have not disabled nor enabled LIRC.
how can i disable lirc?

anyway, i copied and pasted same config file i have with rasplex “stand alone”. so, lirc should be disabled.
this line is commented:

Required overlay for LIRC to function

dtoverlay=lirc-rpi

still can’t get the hifiberry digi to show up in rasplex. any thoughts?

sorry:

Required overlay for LIRC to function

dtoverlay=lirc-rpi

Put a hash (#) in front of:

 dtoverlay=lirc-rpi

Would also suggest you use the latest release 1.0.0 in Berryboot.

yes, lirc is disabled. but yet the hifiberry is not present in rasplex preferences.
don’t know where the problem is.

yes, i’ll switch to rasplex 1.0.x once the problem with downmixing of 5.1 audio is fixed.

Nearly fixed, error found.

When you boot into Raplex does the HiFiBerry status light light up?

I’ll load up Berryboot tomorrow and see if I can get this sorted.

Try this:

Copy the /overlays/hifiberry-digi-overlay.dtb file in normal Rasplex SD card to an /overlays folder on the Berryboot SD card

Replace the bcm2709-rpi-2-b.dtb file on the Berryboot SD with the one in normal Rasplex SD card.

Add the following in the ‘config.txt’ on the Berryboot SD card.

 dtparam=i2c_arm=on

Reboot

hifiberry green light is on.

tried to copy hifiberry-digi-overlay.dtb and bcm2709-rpi-2-b.dtb from rasplex SD to berryboot SD and added
“dtparam=i2c_arm=on”
but the hifiberry is still missing
