Recommendations for Audio Interface to use with Ubuntu and Apple Inc. Macmini3,

[kalpana]

Running Ubuntu 22.04.1 LTS 64 Bit
We have an Icecast2 server and Mixx.
Looking for a reliable compatible audio interface to add microphones w mixer to our radio feed.
Most connections in back of mini are USB.

Any interface suggestions?

Our computer is an Apple Inc. 2009 Macmini3,1 w 4.0 GiB Ram memory and 1 .0 TB Hard Drive.
Intel® Core™2 Duo CPU P7550 @ 2.26GHz × 2
Peripheral connections

• One FireWire 800 port (up to 800 Mbps)
• Five USB 2.0 ports (up to 480 Mbps)
• Audio
• Combined optical digital audio input/audio line in (minijack)
• Combined optical digital audio output/headphone out (minijack)
• Built-in speaker

Though a bit older, she seems to run like a champ.
Thanks,
Gregg Mazel
