Since kernel 3.12 , 3.13 and 3.14, and the latest radeon drivers, I have serious problems with the pulseaudio sound and alsa sound, glitches, skips, so annoying. This problem is not present when I use this kernels with catalyst drivers, are present only when I use opensource drivers.
I have an apu amd a8 5600k.
Please attach your dmesg output and xorg log. For clarity, are you only having problems with dpm enabled? Is this a regression? When was the last working kernel? How are you connecting to your speakers (hdmi, audio jack, etc.)?

the latest kernel that work perfectly was the 3.10 and 3.11 without dpm enabled. the problem is present on 3.12/3.13 and 3.14. I tried it with fedora, ubuntu and archlinux.
I use headphones with jack connection.

Hello, I've just installed a similar FM2 motherboard to this one and am experiencing the same problem with my PCI sound card (Terratec DMX 6Fire), which I bisected to commit 3a118989 "drm/radeon: enable DPM by default in TN asics".
Tried playing with the DPM settings, but to no avail. Issuing an "echo high > power_dpm_force_performance_level" gives me "write error: Invalid argument".
Kernel messages and Xorg logs attached.

Xorg.0.log for AMD A6-6400K.
Audio problem does not occur when booting with "radeon.dpm=0".
the problem still present on kernel 3.16, I need to disable radeon dpm (radeon.dpm=0).
problem continue with kernel 3.17, no changes
Problem does not occur for me in 3.17 if I enable dpm and set "radeon.bapm=1".
radeon.bapm=1 or radeon.dpm?
I only need to set "radeon.bapm=1" to make it work for me. DPM is on by default with my hardware.

here's my Xorg.0.log
I believe that i'm affected too by this issue.
I have attached my logs above.
switching radeon.dpm does not have any effect for me.
trying radeon.bapm to see if this helps.
let me know if there is anything else i can try.
I use HDMI, and pure ALSA.
i used to be affected by this bug -- https://bugs.freedesktop.org/show_bug.cgi?id=77002
but I now think i'm affected by this issue.
but for me, I didn't start noticing it until kernel 3.18.
I too have been utilizing Mesa-git-devel on my system.
but even when I go back to Mesa 10.3.2, i still have this issue.

Does increasing the CPU load help? See:
this seems to be working for me:
i have not had any interruptions -- to date.
now testing with kernel 3.19rc5 -- i will report back to let you know.

i get permission denied when trying to run:
echo high > /sys/class/drm/card0/device/power_dpm_force_performance_level
yes, I am root.
am i doing something wrong?
i have the file > echo high > /sys/class/drm/card0/device/power_method
which has just the word:
should i try changing: default to high
when I try to edit this file with:
echo high > /sys/class/drm/card0/device/power_method
-bash: echo: write error: Invalid argument

Forcing high is not possible on trinity hw. Can you try forcing to low or creating CPU load?
it's actually Richland.
If I set:
is set to default
and, I can set it to High or Low, or any setting:
echo high > /sys/class/drm/card0/device/power_profile
consequently, if I set:
or completely leave it out of grub (default), then,
is set to dpm
and I can not change the profile to anything -- High or Low
hope this makes sense.
not really sure about creating CPU load...?
so..... I've been using the latest drm-next kernel -- http://lists.freedesktop.org/archives/dri-devel/2015-January/076003.html
and so far so good.
I have commented out radeon.dpm and radeon.bapm from grub, and I haven't experienced any sound glitches.
