Appears gunshot sounds may still be broken -- in other words, the fix did not take.
It would be good idea to re-open the original report: http://feedback.dayzgame.com/view.php?id=18245
Kind of surprised it was closed. The whole point of the early access & experimental builds is to test things the devs have done and see if they work. In this case, it does not seem like the fix worked, yet the issue was changed to "fixed" status, preventing any further discussion/comments.
No issues should ever disable further comments in this feedback forum - regardless of status. Just my opinion. Especially since, as Andy pointed out when marking the report fixed, that further development may re-introduce the bug. At the very least, a new "potentially fixed" status should be added to the mix, which encourages people to test the fix and continue to add to the issue report with their test results, confirming or disproving the fix. In my head, it makes sense for everything to stay on one report instead of requiring entirely new reports, so all the facts are collected in one place.
No hate though, love you Andy.
