hello dear community

Yesterday I started up my new raspberry pi 4 and installed it with my DJ programs (MIXXX).
Contrary to my expectations, this worked very well right away.

I just found that there was no waveform.
Hardware information.

The Raspberry Pi 4 Model B is with a Broadcom 2711, Quad-core CortexA72 64-bit SoC @ 1.5GHz
4GB LPDDR4 SDRAM
...
2 x Micro HDMI,
4K video 1 x MIPI
DSI display port
1 X MIPI CSI Camera Port
4-pin stereo audio and composite video
H.265 decode (4kp60)
H.264 decode (1080p60),
H.264 encode (1080p30),
OpenGL ES 1.1, 2.0, 3.0 graphics
...

As a DJ mixer I used the Hercules "serato" externally and as headphones "Raser X-collar" with USB connection.

More information about my software.

Operating system: raspbian full
Music program: MIXXX 2.2.0

Hello ronso,

If you mean the version of the operating system, I have this statement.

PRETTY_NAME = "Raspbian GNU / Linux 10 (buster)"
NAME = "Raspbian GNU / Linux"
VERSION_ID = "10"
VERSION = "10 (buster)"
VERSION_CODENAME = buster
ID = raspbian
ID_LIKE = debian
HOME_URL = "http://www.raspbian.org/"
SUPPORT_URL = "http://www.raspbian.org/RaspbianForums"
BUG_REPORT_URL = "http://www.raspbian.org/RaspbianBugs"

Is your question related to MIXXX so I have this information according to the software center:

-> mixxx-2.2.0 ~ gfsg-1
-> mixxx.data-2.2.0 ~ gfsg-1

a higher version is not yet available and 2.2.3 runs on Ubuntu 18.04

Further information can be found in the appendix
