I have installed /e/os on my Canadian S6, but there seems to be a problem with the modem. I can make and receive calls but there is no call audio whatsoever, I cannot hear them and they cannot hear me.
Is there a work around for this issue? or will /e/rom support this device in the future?
You could try changing the network type under settings. There could be options like LTE , Global . Can you try changing them to see if that makes a difference. Once had a similar problem on a different phone switching to LTE solved the issue.
The differences in models could be a reason. Is there a lineage ROM which works perfectly for your model?
