There's an overview of the audio settings which should be used with the Pi's on-board sound in this sticky.
It's probably related to incorrect settings - see 1., once you have the correct audio settings, the message should disappear.
it might be related to 1. Is the audio played directly by your TV or is it routed to the home cinema ?
Any messages logged in /dev/shm/runcommand.log ? Are you using Steamlink over WiFi or wired ? What's the resolution of your display ?
Then I got 60fps in Steam, but no image. After disabling the Nvidia overlay in the Gforce settings I had an image again but heavy framedrops. After setting Bandwidth limitation in Steamlink itself to "Auto" these were gone as well. Now Rayman is running with 60pfs, what results in no speed change of the game. Why the game reacts so badly on not having 60fps I did not found out.
I figured it out - key is to map the controls in the native emulator (in this case RPCS3) using a keyboard. Then, when playing on the pi via the Steam Link, everything worked great. What a fantastic addition!
@wmarler first of all thanks to your work.
I encountered an issue when using the command make. So when I try to use the commands
make -C /lib/modules/uname -r/build/ M=$(pwd)
$ sudo make -C /lib/modules/uname -r/build/ M=$(pwd) modules_install
its something like :
make : Entering directory ........
make : *** No rule to make target ´ /build/´ . Stop
make : Leaving directory ´ /lib/modules .......
I am quite new to linux on that level so I dont know what to do. Has somebody an idea.
