Re: Bookworm & Direwolf 1.8 not saving sound volumes
One addition here: back on 11/11/23, I had updated
my
doc to include an addition command line option:
?? sudo alsactl --no-ucm store
This was needed to avoid some warnings.? You can learn more about
UCM at:

Hello Arnold,
Raspberry Pi OS Bookworm uses systemd and it should have already
installed the following Systemd unit files to restore your saved
audio levels via:
??? /usr/lib/systemd/system/alsa-restore.service
You can see if it's recognized by running this command:
?? systemctl | grep alsa
?? --
?? alsa-restore.service???????????????????????????????????????
loaded??? active exited??? Save/Restore Sound Card State
?? --
If it's not showing up on your Pi, you need to troubleshoot
that.? There is one noted caveat mentioned in the "1.3 ALSA and
systemd" section in
of why that might happen.? Specifically the
/etc/alsa/state-daemon.conf file cannot exist to let the audio
levels be restored.? Does that /etc/alsa/state-daemon.conf file
exist on your Pi?? If so, do you need it??
Maybe you just saved the audio levels of the wrong souncard card??
Try just running:
?? #saves the levels of all sound devices
?? sudo alsactl save
where this more basic command will save ALL sound device levels
and then reboot.? Did your required levels now get saved?

I have
Direwolf working in a Pi 3B, and I am unable to have the
sound devices volumes get properly restored after a
reboot.
It
receives fine, and transmits fine, and I can adjust
volumes easily using alsamixer, but on the
next power-up, all of the volumes need to get
re-adjusted again.? I can use
sudo
alsactl store 1? (or no channel, or 2 or 3) and
the next power-up the sound devices are messed up yet
again.
I'm
using a usual CM108 sound card, so nothing unusual.

Re: Bookworm & Direwolf 1.8 not saving sound volumes
I too have found this to be an issue with bookworm while running Direwolf 1.7. My guess is that this will also work with 1.8. My workaround was to install pule audio then install pauvcontrol
sudo apt-get install pauvcontrol
This will allow for adjustment of levels.
Default is 100% which is too high. It won't
save settings after reboot.
To set pulse settings permenantly:
pactl get-default-source // make sure default is USB card
// this is for input / rcv
pactl get-default-source
alsa_input.usb-C-Media_Electronics_Inc._USB_Audio_Device-00.mono-fallback
pactl get-default-sink // This is for output / xmit
pactl get-default-sink
alsa_output.usb-C-Media_Electronics_Inc._USB_Audio_Device-00.analog-stereo
FOR INPUT (rcv):
pactl set-source-volume alsa_input.usb-C-Media_Electronics_Inc._USB_Audio_Device-00.mono-fallback 10%
FOR OUTPUT (xmit): pactl set-sink-volume $(pactl get-default-sink) 73%
pactl set-sink-volume alsa_output.usb-C-Media_Electronics_Inc._USB_Audio_Device-00.analog-stereo 73%
These percent settings are for my particular sound card. Re-run each command to adjust the settings to your liking.
This will remember your audio settings for you. This command is only found in bookworm, not in previous OS's.

Re: Bookworm & Direwolf 1.8 not saving sound volumes
Greetings Arnold.
After <F6> and choosing the correct sound card before making
adjustments, then <Esc> to exit, did you "sudo alsactl store"?
Your Rpi may have several audio devces, so <F6> to choose the
correct one is important. If I may ask, please. how did you
determine " alsactl
store 1 " as the correct device?

Re: USB2RIG chinese interface - allegedly soundcard and PTT
Hi Gil,
The Digirig (and presumably the usb2rig as well since it seems to be a clone of the digirig) contains in a really tiny package:
- a bus-powered USB Hub
- a C-Media CM-108 USB Sound Card (but without using GPIO pins) for audio in/out
- a FTDI USB RS-232 interface for both logic level and RS-232 serial rig control
It is ideal for mobile operation due to its light weight, compact size, low power consumption and simple wiring (only one USB cable to the computer to provide power, audio and serial interfaces).
For my purposes, I prefer the DRA-series from Masters Communications but I do understand the purpose of the Digirig devices and if I had a radio with rig-control capability would probably want one.
