[pulseaudio-discuss] Why no 'default device' option?
It's great that *pavucontrol* offers a fallback device option. But why doesn't it offer one for selecting which device would you like to be default? My use case: I'm on a laptop and have a wireless usb headset. I prefer that everything is played/recorded via the headset, when the headset is connected to the laptop. Currently with PulseAudio, every new app that I start will use the onboard sound card. I have to manually go to pavucontrol, and change the streams to my headset. PA will also, at some point later in time, randomly forget that and reset back to the soundcard, but I haven't found the reliable pattern for that to report it. ___ pulseaudio-discuss mailing list pulseaudio-discuss@mail.0pointer.de https://tango.0pointer.de/mailman/listinfo/pulseaudio-discuss

But why doesn't it offer one for selecting which device would you like to be default? Because it doesn't :) Patches welcome. My use case: I'm on a laptop and have a wireless usb headset. I prefer that everything is played/recorded via the headset, when the headset is connected to the laptop. This is a not uncommon request. I'm trying to convince Lennart that this is indeed something we need to expose in the UI. For KDE users this is now possible with PA 0.9.21 and KDE 4.4, but no Gnome UI/interaction exists for this. Currently with PulseAudio, every new app that I start will use the onboard sound card. I have to manually go to pavucontrol, and change the streams to my headset. PA will also, at some point later in time, randomly forget that and reset back to the soundcard, but I haven't found the reliable pattern for that to report it. It's quite predictable actually. PA will always remember what your app has chosen. So if you play something with an app for the very first time, it is assigned to the fallback device (we know no better). Once it's played for the first time, we save that choice. When the app is started next time, it tries to use the same device as last time, and then it uses the fallback. So the randomly forgetting is just using said app with the headset not plugged in. This overwrites your previously saved device. The logic is quite simple, but I have to agree with you that I'd like more predictable results and preferences. An ordered list of priorities per role is what I'd like to see (it's what I've implemented in module-device-manager) with the option to overrule that general choice but with a simple UI to forget the choice and revert to the priority-per-role list.

Well it is rather simple with multiple users... just not at the same time! The multi-seat setup is still rather niche compared to the multi-user setup (e.g. OSX+Windows do the same multi-user stuff we enable OOTB too). Even on multi-seat systems, most of the time each seat has it's own dedicated device (e.g. USB speakers) or similar. This is being dealt with and will be supported with a standard pulse install reasonably soon (whenever the consolekit/udev support is there basically). So really, we're not too bad for the 99% percent of use cases :p Col -- Colin Guthrie gmane(at)colin.guthr.ie http://colin.guthr.ie/ Day Job: Tribalogic Limited [http://www.tribalogic.net/] Open Source: Mandriva Linux Contributor [http://www.mandriva.com/] PulseAudio Hacker [http://www.pulseaudio.org/] Trac Hacker [http://trac.edgewall.org/] ___ pulseaudio-discuss mailing list pulseaudio-discuss@mail.0pointer.de https://tango.0pointer.de/mailman/listinfo/pulseaudio-discuss

Definitely... now that you've explained it to me, the pavucontrol UI communicates it's message quite poorly. Thanks for the tip ___ pulseaudio-discuss mailing list pulseaudio-discuss@mail.0pointer.de https://tango.0pointer.de/mailman/listinfo/pulseaudio-discuss

[pulseaudio-discuss] no clue how to downsample network audio stream + some minor issues
Hello, I'm pretty new to pulseaudio and after some days of reading manuals i'm actually stuck with 3 things: - i have a media server running pulseaudio and i want to stream audio to it. works pretty well so far, but my bandwidth is quite low for the moment so i want to downsample the sound *only* when i use the tunnel sink. i'm stuck here, i don't know where to configure that. daemon.conf (default-sample-rate) doesn't seem to be the right place because it resamples the sound locally as well - what i don't want. - using alsamixer i'm getting a new pulseaudio device by default. that's cool - i thought - so i could map my multimedia keys to amixer to control the volumes... with no success, because alsamixer shows me the volume bar but it doesn't let me change it. why is that and can i enable it somehow? - that led me to take a look at the module-mmkbd-evdev module. But: load-module module-mmkbd-evdev Module load failed. syslog gives me: Nov 26 04:23:39 work pulseaudio[12760]: module-mmkbd-evdev.c: Failed to open evdev device: Keine Berechtigung (no access) to which group do i have to add pulse to make it work? thanks for reading all this :) greetings, vitaminx ___ pulseaudio-discuss mailing list pulseaudio-discuss@mail.0pointer.de https://tango.0pointer.de/mailman/listinfo/pulseaudio-discuss
