I just tried a 15.04 daily and I still get [ 1013.617302] snd_hda_intel 0000:03:00.1: Enabling via VGA-switcheroo [ 1018.648871] snd_hda_intel 0000:03:00.1: Disabling via VGA-switcheroo [ 1018.680852] snd_hda_intel 0000:03:00.1: Cannot lock devices! Is there any difference in the Arch and Ubuntu Kernel that you guys know of, that could cause this "Cannot lock devices"?
Although: Strangely sound seems to be unaffected this time. I enabled the pcspkr driver in modprobe because when I blacklisted it on arch I ran into the same issue. So maybe enabling the beep in the driver would help? Another difference in Arch is, that the AMD card although enabled, does not show up in the the available master channels in the Pulseaudio setting. Further testing revealed that the HDMI / DP Audio is not wired to the AMD sound chip. So disabling it via modprobe with 1,1,0 should leave the Intel DP output running for HDMI audio. (You just have to switch vlc to another audio device). I hope this helps.
