I tested on the latest development version from git://anongit.freedesktop.org/pulseaudio/pulseaudio and it does NOT even work on hotplug, this seems to be because this difference in default.conf: -[Mapping iec958-surround-40] -device-strings = iec958:%f -channel-map = front-left,front-right,rear-left,rear-right -priority = 1 - After some time reading the log I thinks I can at least isolate what could be the important messages: With the _stable_ version it does not work if I plug the device after loading PA: D: alsa-util.c: Trying iec958:1 with SND_PCM_NO_AUTO_FORMAT ...

It looks like it tried the four channel mapping (iec958-surround-40) on iec958:1, but then ends up using hw:1 anyways, but I still haven't figured out the WHY, this is just a hint for when (if) you will look at that. The symptoms looked similar to the unrelated post here: http://www.mail-archive.com/[email protected]/msg04847.html Thanks, Antonio Ospite http://ao2.it -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the QA contact for the bug.
