nom. m. sg. "r"

Just wondering if the r that appears at the end of words is voiced.

For instance: dapr 'sad [nom. m. sg.] would it be pronounce as dap + r or just as dap?
maðr 'man [nom. m. sg.]

I get that the nom. m. pl. "r" is voiced as in draugar. I assume that the nom. m. sg. draugr would also be voiced, otherwise how would you know that it was nom. while having a conversation.

Thanks,
Agnarr

By the way, does anybody even use this forum anymore?
