Hi

Give some information about: your operating system, how far you got through the installation instructions, and what when wrong, Copy and paste any error messages.

Adrian,

Hi I use newest Volumio version Error: volumio@volumio:~$ git clone https://github.com/karlstav/cava fatal: destination path 'cava' already exists and is not an empty directory. I try to reinstall volumio but it didn't work

[antiprism]

The git clone command creates a new 'cava' directory in the current directory and copies the cava code into it. The error message says that that the 'cava' directory already exists, most likely because you have previously run this command.

If you have already installed cava then the following command will succeed (print some help text) and you can move onto the next section fof the instructions

cava -h

Otherwise, delete the cava directory and run the git clone command again (or run the install instructions in a different directory which doesn't have a 'cava' subdirectory).

Thanks for your fast anserw

There is everything okey?

[antiprism]

The instructions don't say to add dtparam=i2c_arm=on to /boot/userconfig.txt. It is probably included in /boot/config.txt, so check there first.

You have missed a 0 in the other line. It should be dtparam=i2c_arm_baudrate=400000 (but you could also try 800000).

Thanks for anserw, I think it will be better if i delte Volumio from SD card and instal again becaus I think I make a lot of mistakes and some times a have issue with me english skiill. Im new in raspberry too

I Reinstall Volumio and now i have this error but before everythink was okay. When display should on? My never do it. Can you make Video tutorial how to install this?

For the first problem, you are running the same command twice. You are in the mpd_oled directory after the first comand.

For the scond problem, your I2C display has not been detected by Volumio. Make sure the OLED is connected correctly and check the I2C configuration section of the mpd_oled installation instructions. If your OLED is not detected mpd_oled cannot work. My output looks like this

     0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f
