Hi Cubii, thank you for the reply. Up to now I skipped the "buttons" topic, because the speaker casing was without the buttons. I am sure that someone will buy your internals on ebay, you have to be patient. I found your offer on ebay and think that 70 is a little bit high considering that you get a complete speaker for 99 at IKEA, incl. die Wifi antennas, buttons, power adapter, which is not included in your offer...
In regard of my installation it is working now! One problem was, that I had to switch the left and right channel. Obviously I connected the drivers the wrong way round to the Amp terminals. Instead of switching the wires in the case I changed the asound.conf. This is the part I changed (at the end of the file) From: Code: -------------------- ttable { 2.0 0.5 # Mix stereo low signal to mono (mid-range) 3.0 0.5 4.1 0.5 # Mix stereo high signal to mono (tweeter) 5.1 0.5 } -------------------- To: Code: -------------------- ttable { 2.1 0.5 # Mix stereo low signal to mono (mid-range) 3.1 0.5 4.0 0.5 # Mix stereo high signal to mono (tweeter) 5.0 0.5 } -------------------- To answer my previous questions: - Do I need to modify the asound.conf? No, not needed. The one from the tutorial should work. - Can I use the pre-compiled extension rt-plugins for pCP 8.2.0? Yes. - How can I check that the extension is working? Still don't know that. - Was is right to activate the ladspa extension? No, this is not necessary. I de-activated it. I also activated the "ALSA 10 band Equalizer" in Tweaks -> Audio tweaks. Not sure if I did that before... I wish everyone a Merry Christmas. Thanks for the support. I case someone is in need of it I attached the files from https://www.linux-magazine.com/Issues/2020/239/Rasp-Pi-Symfonisk 39547 Jörg +-------------------------------------------------------------------+ |Filename: speaker-conversion.zip | |Download: http://forums.slimdevices.com/attachment.php?attachmentid=39547| +-------------------------------------------------------------------+ ------------------------------------------------------------------------ joerg74's Profile: http://forums.slimdevices.com/member.php?userid=73258 View this thread: http://forums.slimdevices.com/showthread.php?t=117272
