> @aivanov-jdk, thank you very much for your review, JDK-8301846 helps for fixing _Primary Sound Driver_ recording device name truncation issue.

I referred to JDK-7116070. The root cause of that problem seems to be same as this one. While you and the reviewers have all the context, I suggest looking into JDK-7116070 in more details to understand why there are still devices, or rather *ports*, with truncated descriptions.
