I'm wondering if anyone else has found this issue. When I install a nightly build dated after May 24, my device loses all audio-no ringer, no audio notifications, no music. I've had the same result with the May 26 and May 29 builds. When I attempt to restore from Safestrap I get an MD5 mismatch. As soon as I reapply the B37, May 24 nightly, everything works and there are no longer any issues. Thanks.
