I enabled USB audio and then added the following to triggerhappy to control the volume and it sort-of works. I believe this may be due to the output of the encoder or triggerhappy missing events.
REL_WHEEL -1 /var/www/vol.sh -dn 1
REL_WHEEL 1 /var/www/vol.sh -up 1
If I very slowly scroll I can usually increase/decrease the volume by 1. If I go too fast the volume will go to 0 and start over. At this point I'm not sure if this is an interrupt issue with triggerhappy.
I saw the same jumpy behavior a while ago with a DROK USB volume control. At the time, I thought it might be the DROK, but perhaps it's related to triggerhappy after all.
