This is what happens on OpenBSD 5.2-current (GENERIC.MP) #15: Fri Jan 11 16:41:47 MST 2013
$ env SNDIO_DEBUG=1 play file.mp3 aucat_open: host= unit=0 devnum=0 opt=default /tmp/aucat-1000/aucat0: No such file or directory aucat: start, maxwrite = 0 file.mp3: File Size: 4.52M Bit Rate: 128k Encoding: MPEG audio Channels: 2 @ 16-bit Samplerate: 44100Hz Replaygain: off Duration: 00:04:42.96 In:0.00% 00:00:00.00 [00:04:42.96] Out:0 [ | ] Clip:0 aucat: flowctl = 8820, maxwrite = 35280 aucat: flowctl = 882, maxwrite = 3528 aucat: flowctl = 882, maxwrite = 3528 aucat: flowctl = 882, maxwrite = 3528 aucat: flowctl = 882, maxwrite = 3528 [...] The audio plays fine, but why is this: /tmp/aucat-1000/aucat0: No such file or directory Indeed, there is no /tmp/aucat-1000/aucat0 (1000 is my userid), but there is /tmp/aucat/aucat0; is this something from the past of sndio, when it used userid in the socket name?
