I am attempting to run several Ham Radio apps in a guest Ubuntu 22.04.1, on a MBP MacOS (Catalina) host. I’ll explain why later if it is of interest. These apps need access to a combo USB audio codec and serial port device called DigiRig. I do not know how to make these interfaces available within the VM for these apps. In Linux, the apps would use plughw:X,Y for audio and /dev/tty.<etc.> for serial port. One of the apps is an AFSK modem called “ARDOPC”. I’m very new to QEMU, and might have gotten in too deep too quickly with the command line. I’m using the following command script cobbled together from several posts: ``` qemu-system-x86_64 \ -m 4G \ -vga std \ -display default,show-cursor=on \ -usb \ -device usb-host,vendorid=3468,productid=316 \ -device usb-tablet \ -smp 2 \ -drive file=ubuntu.qcow2,if=virtio \ -cpu host \ -machine type=q35,accel=hvf \ ``` The QEMU emulator version 7.2.0 with Ubuntu seems to work fine, but aplay and arecord -l show no audio devices. Any suggestions would be appreciated. New Call; N1YB, but haven’t changed my login on groups.io. - Gary

I have seen the s390x version of qemu mentioned at various points. Does qeme supporting s390x run anything besides an s390x Linux guest? Harold Grovesteen
