http://bugzilla.opensuse.org/show_bug.cgi?id=980923 Bug ID: 980923 Summary: cmus playback fairly slow and stuttering Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: Other OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: Sound Assignee: tiwai@suse.com Reporter: maiktapwagner@aol.com QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- Dear openSUSE-Team, Current Tumbleweed installation with LXDE here. I am trying to playback audio mp3-Files which in general works great but only using "Videos" (totem). I tried a basic console application called "cmus" and noticed that the sound is stuttering a lot and suffers from lags. mwagner@linux-6s7s:~$ /sbin/lspci | grep Audio 00:01.1 Audio device: Advanced Micro Devices, Inc. [AMD/ATI] Kabini HDMI/DP Audio 00:14.2 Audio device: Advanced Micro Devices, Inc. [AMD] FCH Azalia Controller (rev 02) Could you look into this, please? Regards, Maik -- You are receiving this mail because: You are on the CC list for the bug.

Also, which output are you testing? The onboard analog one (e.g. headphone) or over HDMI? The stuttering with AMD chip may come due to the cache coherency issue. Try to pass snoop=off option to snd-hda-intel module, e.g. set the line below in /etc/modprobe.d/50-hda.conf: options snd-hda-intel snoop=off and reboot the system and retest. Last but not least, give more detailed hw information, e.g. the output of alsa-info.sh script. Run it with --no-upload option and attach (don't paste) the output file to Bugzilla. -- You are receiving this mail because: You are on the CC list for the bug.

http://bugzilla.opensuse.org/show_bug.cgi?id=980923 http://bugzilla.opensuse.org/show_bug.cgi?id=980923#c2 --- Comment #2 from Maik Wagner --- Created attachment 677815 --> http://bugzilla.opensuse.org/attachment.cgi?id=677815&action=edit alsa-info.sh script output Hello Takashi, thanks for getting back to me so quickly. As requested I provide further information. Kernel is 4.5.4-1-default according to "uname -r" I am using the analogue output as my monitor doesn't have speakers. I am also attaching the output of the alsa-info.sh script. Thanks for the pointer to this. I wasn't aware that such a script exists. Unfortunately I do not have such a file called: /etc/modprobe.d/50-hda.conf - Shall I create such a file and put the line you indicated there?

The stuttering with AMD chip may come due to the cache coherency issue. Try to pass snoop=off option to snd-hda-intel module, e.g. set the line below in /etc/modprobe.d/50-hda.conf: options snd-hda-intel snoop=off

and reboot the system and retest.

I tried this but this resulted in having no audio at all. pavucontroll defaults to Dummy-output and doesn't show any audio hardware at all. -- You are receiving this mail because: You are on the CC list for the bug.

That's odd. Could you give dmesg output? Also try snoop=0 instead of off, just to be sure. -- You are receiving this mail because: You are on the CC list for the bug.

If I am getting the cmus package from the packman repository, should I continue filing the bug report here or message the packager directly? -- You are receiving this mail because: You are on the CC list for the bug.
