Notebook: yes Internal 5.1? I don't believe so. Headphone, mic, line in? Yes. > 1) large volume range of mic capture > Volume and speaker playback volume > > https://git.kernel.org/cgit/linux/kernel/git/tiwai/sound.git/commit/sound/usb/mixer.c?id=9b4ef97757953c6071563b7cbfc689e3dd771603 Are you saying there is a large range on the internal mic? or on the USB mic? > 2) your 5.1 internal speaker have same priority Which priority are we discussing? Somewhere in udev? In pulse audio? Or in the KDE audio setup? And this original thread wasn't about speakers. The USB out works fine, every time. My issue is this: when I try to hotplug the USB headset, it comes up as a *output* device only, instead of also detecting the mic. Also, this worked flawlessly in Ubuntu 12.04 (pulse-audio 1.1, kernel 3.2-3.8). It is only since upgrading to pulse-audio 4.0 and kernel 3.13.x that i have a problem. j -- Joshua J.
