initializing alsa soundcard levels at startup

Does the hamvoip allstar system automatically restore alsa sound card levels on startup or system boot and if so, from what file is it restoring the levels and where is that call to alsactl (I suspect) made?

Since you are using the hamvoip version, you may get better support for this type of question through their list. Since they have chosen to make their releases not open source no one other than those developers can accurately know what their system is doing.

Hi Doug,

Just like all versions of AllStar, the audio levels for the
Asterisk/AllStar application are set directly by the channel driver each
time the driver resets, including when it loads initially.

To adjust these levels, use the simpleusb-tune-menu program, which adjusts
the levels real-time and will let you save your settings.

The audio level settings get saved to a config file in the /etc/asterisk
folder, with naming conventions like: simpleusb_tune_*.conf ....In this
case, the star ("*") is the name of the device you used. So, if the device
was named "usb0" the file would be: simpleusb_tune_usb0.conf
