I tested by watching YouTube videos (Firefox + Adobe Flash plug-in), watching clips with Totem, launching
gst-launch-1.0 uridecodebin uri=file://<path to music file> ! pulsesink and gst-launch-1.0 uridecodebin uri=file:///<path to music file> ! alsasink and aplay <path to WAV file> Same result. I take pride in not being an MPlayer user, however, the above tests made with GStreamer and alsa's aplay seem to show that the problem is not in Pulseaudio but in the audio drivers. How do I know whether my hdmi lcd monitor has EDID? It is fairly modern, and it worked when Ubuntu 13.04 was installed. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1245226 Title: HDMI: audio-video playback too fast Status in “alsa-driver” package in Ubuntu: Incomplete Bug description: After upgrading to Ubuntu 13.10, selecting HDMI as audio output device is broken. Audio is played back at high speed. When playing back video clips, the video frames are also too fast. This is similar to an old bug I reported some time ago, https://bugs.launchpad.net/ubuntu/+source/linux/+bug/897008 . In that case, adding radeon.audio=1 to the kernel command line solved. Now, the configuration is unchanged since when Ubuntu 13.04 was running $cat /proc/cmdline BOOT_IMAGE=/boot/vmlinuz-3.11.0-12-generic root=UUID=10b9da6b-d735-48a7-bc45-2c1fc81183dd ro quiet splash radeon.audio=1 vt.handoff=7 yet audio is broken. Note that, when selecting headphone as audio output device, everything works.
