Hi, I'm having this issue in KMix for ages now. Take a look at the attached screenshot. Reproducible: Always Steps to Reproduce: Don't know. Just happens. Actual Results: At every single boot i get those annoying KMix popups that KMix picked another audio device followed by another one to revert. Expected Results: KMix should just work i guess. Some technical details: KMix version: Qt: 4.8.1 KDE Development Platform: 4.8.3 (4.8.3) KMix: 4.1 Hardware (lspci): 00:00.0 Host bridge: Advanced Micro Devices [AMD] RS880 Host Bridge 00:02.0 PCI bridge: Advanced Micro Devices [AMD] RS780 PCI to PCI bridge (ext gfx port 0) 00:05.0 PCI bridge: Advanced Micro Devices [AMD] RS780/RS880 PCI to PCI bridge (PCIE port 1) 00:07.0 PCI bridge: Advanced Micro Devices [AMD] RS780 PCI to PCI bridge (PCIE port 3) 00:09.0 PCI bridge: Advanced Micro Devices [AMD] RS780/RS880 PCI to PCI bridge (PCIE port 4) 00:0a.0 PCI bridge: Advanced Micro Devices [AMD] RS780/RS880 PCI to PCI bridge (PCIE port 5) 00:11.0 SATA controller: Advanced Micro Devices [AMD] nee ATI SB7x0/SB8x0/SB9x0 SATA Controller [AHCI mode] (rev 40) 00:12.0 USB controller: Advanced Micro Devices [AMD] nee ATI SB7x0/SB8x0/SB9x0 USB OHCI0 Controller 00:12.2 USB controller: Advanced Micro Devices [AMD] nee ATI SB7x0/SB8x0/SB9x0 USB EHCI Controller 00:13.0 USB controller: Advanced Micro Devices [AMD] nee ATI SB7x0/SB8x0/SB9x0 USB OHCI0 Controller 00:13.2 USB controller: Advanced Micro Devices [AMD] nee ATI SB7x0/SB8x0/SB9x0 USB EHCI Controller 00:14.0 SMBus: Advanced Micro Devices [AMD] nee ATI SBx00 SMBus Controller (rev 41) 00:14.2 Audio device: Advanced Micro Devices [AMD] nee ATI SBx00 Azalia (Intel HDA) (rev 40) 00:14.3 ISA bridge: Advanced Micro Devices [AMD] nee ATI SB7x0/SB8x0/SB9x0 LPC host controller (rev 40) 00:14.4 PCI bridge: Advanced Micro Devices [AMD] nee ATI SBx00 PCI to PCI Bridge (rev 40) 00:14.5 USB controller: Advanced Micro Devices [AMD] nee ATI SB7x0/SB8x0/SB9x0 USB OHCI2 Controller 00:16.0 USB controller: Advanced Micro Devices [AMD] nee ATI SB7x0/SB8x0/SB9x0 USB OHCI0 Controller 00:16.2 USB controller: Advanced Micro Devices [AMD] nee ATI SB7x0/SB8x0/SB9x0 USB EHCI Controller 00:18.0 Host bridge: Advanced Micro Devices [AMD] Family 10h Processor HyperTransport Configuration 00:18.1 Host bridge: Advanced Micro Devices [AMD] Family 10h Processor Address Map 00:18.2 Host bridge: Advanced Micro Devices [AMD] Family 10h Processor DRAM Controller 00:18.3 Host bridge: Advanced Micro Devices [AMD] Family 10h Processor Miscellaneous Control 00:18.4 Host bridge: Advanced Micro Devices [AMD] Family 10h Processor Link Control 01:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI Barts XT [ATI Radeon HD 6800 Series] 01:00.1 Audio device: Advanced Micro Devices [AMD] nee ATI Barts HDMI Audio [Radeon HD 6800 Series] 02:00.0 USB controller: NEC Corporation uPD720200 USB 3.0 Host Controller (rev 03) 03:00.0 FireWire (IEEE 1394): VIA Technologies, Inc.

RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 06) and i'm having this issue for ages! Certainly as long as i've been using Archlinux. (which is years by now) Everything is fully up to date. The system is using Pulseaudio and was using Alsa. I thoroughly removed alsa configuration files and runtime applications. The libs are still on since some applications sadly can't start without (chrome for example). Kinda important to know. If i start my computer and login the first time i get the described issue. If i logout and back in, it works! Then if i reboot again it starts all over again and doesn't work anymore. So this happens Every time at boot with the first login!

This is not kmix but phonon. I'd recommend opening a bug against your distro and let your packagers debug the problem and push any fixes/suggestions upstream.

Hi, If i where using a distribution that tends to customize a lot of things i would agree. However, i'm using Archlinux which tries to stick to upstream as close as possible (and that's working quite well) so i'm inclined to think that this is an issue in KDE (phonon) somewhere rather then Archlinux. I will also ask the archlinux guys (just to be sure) to see if they know of this issue and might have a solution for it. Cheers, Mark
Right, more information. It "seems" that HDMI is in the way. If i disable HDMI output i'm not getting a confused KDE anymore so that might be a possible issue somewhere.
And which exact Phonon version is this about?
(In reply to comment #5) > And which exact Phonon version is this about? Quite difficult to see so i'm guessing the library version will do. This seems to be phonon 4.6.0
Actually, when I said "phonon" I guess I really meant "bits of phonon in kde runtime". It's all rather complicated how it all glues together (and I've forgotten most of the details myself), but I believe this is actually something that is not specifically *in* phonon but one of the components that live in e.g. kde-runtime that works with it. IMO It should really be purged, as this kind of dialog is only really relevant when PulseAudio is not used and it seems to be kicking in here incorrectly. I guess a bit more work is needed on that stuff to shut it up when PA is there... but I guess it still needs to exist in some capacity for the cases when it is not.

Hi I have the same problem with KMix on KUbuntu 12.04 precise pangolin distro. It seems to be independent by the distro. Regards
Is this still reproducible with KDE 4.10.2?
(In reply to comment #9) > Is this still reproducible with KDE 4.10.2? Hi, Yes it is but it's a bit different now. I have a usb microphone (corsair vengeance 1500) which i had one time plugged in my machine at boot. Linux and KDE started up fine and sound was blasting out of the headphone just fine as one would expect. However, every time i boot my pc now without that headphone i get the kde message that it can't find "corsair vengeance 1500" even if i tell it to just forget the thing. However, right now it falls back just fine to the normal speakers. So the issue - as reported - is gone, but there is still "a" issue somewhere in picking audio output devices.

You could try erasing the existing phonondevicesrc file located in $HOME/.kde/share/config/ (might be $HOME/.kde4/share/config/ on some systems). Ideally you should do that from a shell when logged out, so it is rebuilt for the actually connected hardware. Or you edit that file and remove the headphones from there.
