Hi Changeset 4852, "Avoid setting sound device if sound devices are the same" is breaking wave file playback for me. I am using NULL sound device which closes automatically after idle for 1 second ( snd_auto_close_time setting ). The sound device is not opened again during conference of the call with wave player because the device hasn't changed. I tried setting snd_auto_close_time = -1 and it works but the playback is intermittently delayed by several seconds. What am I missing?
