[pulseaudio-discuss] [PATCH v2 0/5] Add default volume to ports

[Tanu Kaskinen]

This is pretty much a complete rewrite of the patches that intended to
fix bad volume behaviour on Terratec Aureon Dual USB. These patches
add a new default volume attribute to ports and alsa-mixer paths, and
use that to fix the Aureon volume bug[1].

The default volume of all analog paths, not just Aureon, is now 30%
instead of 100%. Also, the port default volume is now considered when
switching ports. That means, for example, that on the first boot of
a laptop with speakers and a headphone jack (unplugged), the speakers
get their default volume set as before (based on the hardware volume),
but when plugging in headphones, the sink volume jumps to 30%. That's
a good thing, because the speaker volume won't affect the default
headphone volume like it has affected so far.

Here's a link to the v1 patch set discussion, where the device default
volumes were discussed in some length:
