I have a queer issue with my Arch-Linux System. I am unable to get any Sound Output when playing audio, AFTER starting X Server.The issue is not with Volume Controls or Sound Card Drivers because, if I start any kind of Audio playback BEFORE starting X Server, I have absolutely no issues. The Audio keeps playing even after X Server starts. But if I pause / stop the audio, on restarting playback, I get no audio output. Even terminating X Server does not resolve this issue. Rebooting the system though, helps.I tried with different DE's. Checked with GNOME, XFCE, LXDE, KDE. Same issue everytime. So It's not due to a particular environment, but rather an issue with X. I am not sure what files I should be checking for this. Could any please guide me through?
No Audio Output with X11
arch linux;x11;audio
Finally solved this problem thanks to help rendered on the #archlinux IRC Channel. The issue was that for some odd reason, starting X would change the default Audio Output Device to my HDMI Card which was not being used to output audio.On Arch Linux, I installed the package pavucontrol for PulseAudio and used it to reset the default device for audio playback to my on-board sound card.
