We need to fix it (ie make the device appear play-only), but I don't have a machine that reproduces the problem. If you have some time, could you build a kernel with the AZALIA_DEBUG option, reboot using the new kernel and send me the output of dmesg once with the mic disabled in the bios and once with the mic enabled. This way we could compare them and possibly find a fix. thanks

Okay, I'm in a somewhat lazy summer holiday mode here, and recent political events may have made me a little jumpy, but at this point I would seriously consider cutting the wires to the hardware microphone so as to see if audio will start stuttering againg.. :-D -- Erling Westenvik

Good question! Just tried a regular pop song MP3 and got the same stuttering. Here's the mplayer output: === Requested audio codec family [mpg123] (afm=mpg123) not available.

how would you troubleshoot stuttering video? (Lenovo Thinkpad)
Lenovo ThinkPad T440s : just a couple years old. Triple-booting Arch Linux and Windows too, it's plenty fast to watch even huge HD 1080p movies. But on a new stock OpenBSD (dmesg below) it does that stuttering thing with all video, even the tiniest little YouTube or low-resolution mp4 file, even if only 3 seconds long: "ev.. er...y th... ing... stut... ters... a... few... times... per... sec... ond...", whether using mplayer or browser or any other method I've tried. I saw http://www.openbsd.org/faq/faq13.html#audioserver and tried the `rcctl set sndiod flags -b2400` advice with various frames values, huge and small, but it had no effect. Any pointers for what you'd look at, if it were you, to troubleshoot this? I'm happy to do the work, but sorry I don't know where to start.
