#872: Loss of sound with two sink inputs ---------------------+------------------------------------------------------ Reporter: AdamK | Owner: lennart Type: defect | Status: new Milestone: | Component: daemon Resolution: | Keywords: ---------------------+------------------------------------------------------
Comment(by coling): Could this be a result of artefacts from the "Flat Volumes" feature? (pulseaudio will always try and use h/w volume whenever possible to reduce overhead and thus power consumption etc - and thus when there is only one stream playing, the volume of that stream will always be the same as the underlying alsa volume - although the concept of a "system volume" is still maintained and presented to the user even if it's not really used like that underneath!) To test this, load up alsamixer -c0 and have a look at the bars for Master and maybe PCM too. When your second "sink input" (source is not the right term as a "source" is a recording device - e.g. a mic. I've fixed the summary to reflect this.) starts (and you hear your dropout), do you see them jump about a bit? If so, you can work around this by disabling flat-volumes in daemon.conf. Git master already has support to minimise the fallout from this - which stems from there being no way to synchronise mixer changes in alsa - so if this is the problem you are seeing, it's likely fixed already :) -- Ticket URL: <http://pulseaudio.org/ticket/872#comment:1> PulseAudio <http://pulseaudio.org/> The PulseAudio Sound Server _______________________________________________ pulseaudio-tickets mailing list pulseaudio-tickets@mail.0pointer.de https://tango.0pointer.de/mailman/listinfo/pulseaudio-tickets
