Both gst-launch-1.0 and aplay work if the default device is set to analog headphones in gnome-control-center, and do not work correctly if the default device is set to HDMI.
I tried the following: speaker-test -c2 -t wav -D hdmi:1,DEV=0 gst-launch-1.0 uridecodebin uri=file:///<path to music file> ! alsasink device=hdmi:1 and the sound is too fast in both cases.

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.
