Hi All, and thanks to all, again, I've solved for the moment, even if I think this is not the way the system should work.
But I want to _underline_ that I assume the position of a normal, average user (eg., my mom or the grandpa) who cannot fight against these simple (for geeks) but thorny issues. I forward the answer I received from Colin as reply of my bug report (I consider it a bug). In many ways, the workaround is the same other users gave to me, with some explanation and link more. JFYI... cheers! :-) --------- Messaggio inoltrato --------- Oggetto: [Bug 254016] KMix with Pulseaudio doesn't show channels in config channel dialog after upgrading to Kubuntu 10.10 Data: mercoledì 13 ottobre 2010, 00:41:52 Da: Colin Guthrie <[email protected]> A: [email protected] https://bugs.kde.org/show_bug.cgi?id=254016 --- Comment #2 from Colin Guthrie <cguthrie mandriva org> 2010-10-13 00:41:51 --- Hi there, Everything will work for you but you need to make a couple configuration changes to get things working really nice :) Have a look over this page: http://pulseaudio.org/wiki/KDE In order to get a 5.1 configuration, you need to change the Hardware Profile. Sadly Kubuntu ships without the utility I wrote to do this in KDE (due to time constraints). You can see this UI here on my blog: http://colin.guthr.ie/2010/07/speaker-setup-now-or-forever-hold-your-peace/ but this isn't much use to you right now! This means you need to install another utility. So use the installer system (I don't use Kubuntu so I don't know the exact instructions here) and install "pavucontrol". With this utility you can go to the "Configuration" tab and select an appropriate "Hardware Profile" for you sound card. I'd imagine you want to pick a 5.1 configuration. You only have to do this once. It will be remembered. You can then use KMix to adjust each individual channel by right clicking on the device and selecting the "Show Channels" option from the context menu. This will give you full control over each channel. PulseAudio tries to simplify the whole audio process. Most people don't really understand all the separate ALSA controls that used to be displayed in KMix. And even for those that did, controls that are not relevant to the current use (e.g. the rear channels when playing stereo to front speakers only) were permanently displayed which is not ideal. Sadly it wasn't that easy to squeeze PulseAudio support into the KMix constructs. For example the Show Channels dialog that you show in your screen shot it really misnamed when using PA. It would be better labelled "Configure Devices and Controls" which would be more representative of its function (even calling it channels in ALSA is an oversimplification IMO). Sadly I could not label the individual channels in KMix (front left, front right etc.), but you can use pavucontrol to see labels if you need them (it's perfectly safe to run them both at the same time and a change one application should be immediately reflected in the other. Hope this helps. -- Configure bugmail: https://bugs.kde.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You reported the bug. ------------------------------------------ -- Valter Registered Linux User #466410 http://counter.li.org Kubuntu Linux: www.kubuntu.org OpenOffice.org: www.openoffice.org -- kubuntu-devel mailing list [email protected] Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/kubuntu-devel
