Bug 76837

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.

dmesg output

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.

Cheers,
Martin

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".

Cheers,
Martin

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.

Martin

Xorg.0.log

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:
https://bugzilla.kernel.org/show_bug.cgi?id=86351

this seems to be working for me:
radeon.bapm=0 radeon.dpm=0
kernel 3.18.3

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:
default

in it.

should i try changing: default to high
?

when I try to edit this file with:
echo high > /sys/class/drm/card0/device/power_method

i get:
-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:
radeon.bapm=0 radeon.dpm=0

then,
/sys/class/drm/card0/device/power_method
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: 
radeon.bapm=1 radeon.dpm=1

or completely leave it out of grub (default), then,
/sys/class/drm/card0/device/power_method
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.
