I'm currently testing ardopcf and QtSoundModem with an IC7100 on a Pi4.
I had to make a change to ardopcf to get it to open the dsnoop device (it reported can't set sample rate).
Once I'm happy that is it working I'll publish the patch to ardopcf and the ALSA configuration. It may not be for a few days as I'm away sailing at the moment.

You can run both ardopc(f) amd QtSoundModem at the same time. On Windows it is trivial, as Windows allows sharing a sound card. The Linux ALSA hw: driver does not let you share the same soundcard with multiple applications, but there are ALSA plugins DMIX and DSNOOP which will combine streams. Pulseaudo will also allow sharing, but has it own problems.
Configuring DMIX and DSNOOP can be a bit complicated, especially if your soundcard does not directly support a sample rate of 12000. I'm still trying to get it to work, but I'm pretty sure others have and hopefully will post their configurations.

Hi, John:
Thanks.
All/any:
I have QtSoundModem running on a mini-laptop with:
pi@nc8q-qj:~$ cat /etc/os-release
NAME="Linux Mint"
VERSION="21.1 (Vera)"
ID=linuxmint
ID_LIKE="ubuntu debian"
PRETTY_NAME="Linux Mint 21.1"
VERSION_ID="21.1"
HOME_URL="
SUPPORT_URL="
BUG_REPORT_URL="
PRIVACY_POLICY_URL="
VERSION_CODENAME=vera
UBUNTU_CODENAME=jammy
Which uses the serial IO of an IC-7100 on 40 or 20 meters.
QtSoundModem runs 300bd;(2) AX.25 and (2) IL2P modems, each on separate audio sub-bands.
IOW, While there might be others using 7103.3c kHz AX.25, I can forward/receive on 7104.3c IL2P
without interfering.
QtSoundModem and pilinBPQ share an AREDN node for LAN/DHCP.
So, in addition to HF ports, it is connected to a local SHF network of 30+ nodes.
I need to read-up on DMIX and DSNOOP.
If there are instructions leading to how to run QtSoundModem and ARDOPCF on an IC-7100,
please tell me where.
73, Chuck
