Waiting for more people to review and accept the patch. - Updated sound(4) man page, as well as Wiki page. - Reviewed https://reviews.freebsd.org/D44469 and used the function in D44411. - Added support for the OSSv4-compatibility alias devices. Disallowed access to /dev/dspX.[v|r|vp|vr]Y device. See related discussion in previous report, as well as the comments in the review. - More testing. Also continued the asynchronous device detach patch: https://reviews.freebsd.org/D43545 - Updated and simplified diff, now depends on D44411. - Debugging a kern_poll() panic occuring after hot-unplugging the device with jackd running. - Closed https://reviews.freebsd.org/D11140 since D43545 takes care of this change. Lastly, I gave a talk at AsiaBSDCon in Taipei, Taiwan. Christos
