Hi,

I want to thank everyone here for their efforts and to share what ultimately worked for me.
SBC: pi 4, 4gb ram
OS: Linux LibreELEC 5.10.110
SteamLink version: steamlink-rpi3-1.2.0.241.tar.gz
Audio: HDMI PCM stereo

Followed OP's directions:

I wanted to try steamlink without reinstalling anything, so after about an hour of screwing around here is how I got it working.

This only makes changes within /storage/steamlink , nothing else is touched. If you do not have at least a novice understanding of linux shell or don't fully understand the commands here DO NOT ATTEMPT.

First thing we download the newest Steamlink and extract it (run on rpi)

Code

Code

cd /storage
wget "$(wget -q -O - http://media.steampowered.com/steamlink/rpi/public_build.txt)"
tar -zxf steamlink-rpi3-1.2.0.241.tar.gz

Next we need to download the missing libs that aren't included in this or libreelec itself. These commands might work within the rpi itself but I did them on my desktop.

Code

Code

curl --header 'Host: director.downloads.raspberrypi.org' --user-agent 'Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:63.0) Gecko/20100101 Firefox/63.0' --header 'Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8' --header 'Accept-Language: en-US,en;q=0.5' --header 'DNT: 1' --header 'Upgrade-Insecure-Requests: 1' 'http://director.downloads.raspberrypi.org/raspbian_full/images/raspbian_full-2018-11-15/2018-11-13-raspbian-stretch-full.zip' --output '2018-11-13-raspbian-stretch-full.zip'
unzip 2018-11-13-raspbian-stretch-full.zip
rm -f 2018-11-13-raspbian-stretch-full.zip
mkdir x
mount -o loop,ro,offset=50331648 -t ext4 2018-11-13-raspbian-stretch-full.img x
cd x
for i in libpng16.so.16 libicui18n.so.57 libicuuc.so.57 libicudata.so.57 libX11-xcb.so.1 libX11.so.6 libXext.so.6 libxcb.so.1 libxkbcommon-x11.so.0 libXau.so.6 libXdmcp.so.6 libxcb-xkb.so.1 libbsd.so.0; do cp "$(find -name $i)" .. ; done
cd ..
umount x
rmdir x

Now we have extracted all the libs we need from raspbian, next step is to transfer them into steamlink's /lib folder (the hostname will be different for your setup)

Code

Code

scp lib* root@rpi3:/storage/steamlink/lib/

Next we need to install the steamlink udev rules, but udev is readonly, so we just overlay it (run from rpi)

Code

Code

mkdir /storage/steamlink/overlay_work
mount -t overlay overlay -o lowerdir=/lib/udev/rules.d,upperdir=/storage/steamlink/udev/rules.d/,workdir=/storage/steamlink/overlay_work /lib/udev/rules.d
udevadm trigger

Now the steamlink.sh that comes with it is not geared for libreelec, so copy this one over it

This worked well except that I had no audio output at all the following modifications were required:

Quote

Audio didn't work. I figured it was because I was testing with a linux host but it didn't work in windows either.

To fix add this to your config.txt

Code

Code

mount -o remount,rw /flash
nano /flash/config.txt
### add this then reboot
dtparam=audio=on

Then use this new steamlink.sh that does the udev stuff automatically and loads pulseaudio before steamlink

Which led me to getting garbled sound on the analogue audio jack only, adding the following lines in the steamlink.sh file:

# start pulseaudio
echo 'starting pulseaudio'
pulseaudio -k 2>/dev/null
cat /etc/pulse/default.pa | sed 's/^\(load-module module-udev-detect\|load-module module-detect\)/\1 tsched=0/' > /storage/steamlink/pulse_default.pa
pulseaudio -D -n -F "$TOP/pulse_default.pa"
# The next line is used for setting the audio output device. To obtain a list of posible values
# run 'pulseaudio -d', then 'pactl list sinks' which will list all availible output devices, use 
# the name: field of the desired output as the argument for the following command. 
pactl set-default-sink alsa_output.1.hdmi-stereo

And that's it, works perfectly!
