[solved] Weird sound from speakers on kde
I am hearing weird noises from my speakers... like somebody is wraping plastic
I use Gstreamer and I think I have an intel sound card (its intergrated into the motherboard)

Re: [solved] Weird sound from speakers on kde
Musmula, you provide no relevant information on the hardware. Is this a laptop? Are those external speakers? Do you use ALSA, OSS, Pulseaudio, JACK, etcetera, etcetera?
aplay -lL;
lspci -vnn | grep -A1 -i audio;
cat /proc/asound/modules;
for i in $(awk '{print $2}' /proc/asound/modules | sort | uniq); do echo "--- $i ---"; systool -vm $i; done;
lsmod | grep ^snd;
fuser -v /dev/snd/*;
for i in /proc/asound/card[0-9]*; do echo "--- $i ---";amixer -c $(cat $i/id); done;
lsusb #if there is a usb sound card;
# or use the alsa-info scriptSince you probably have pulseaudio running, kill it. Does the sound go away? Check all hardware connections, preferably also inside of this desktop/laptop. Does the sound persists during boot up, meaning when you are in BIOS/UEFI and grub? If you have any audio devices connected, disconnect them. Try to narrow the source down. Amixer in the script above, will show volume levels and controls status. Check if you have levels at a high gain (> +20 dB).

Re: [solved] Weird sound from speakers on kde
It is a desktop PC, I use pulseaudio, I killed the process and nothing changed... the process started again after a little while and I hear the noises again.
I dont hear them in BIOS nor have I heard them on any other OS I used in the past 2 years (windows xp-8, Ubuntu 12.04-14.04, Linux lite, #!, DSL, Fedora 20) and I think I didnt hear them when I was using xfce (I use KDE now) on arch. Here is the output of that script of yours:

btw
Youtube, VLC and Dragon player behave weird as well. Youtube doesent want to load videos sometimes, at the same time Dragon player is stuck at the same frame no audio, VLC plays video but no audio and when I open a video i MPlayer it works fine and youtube starts working again

Re: [solved] Weird sound from speakers on kde
You can disable autospawn of PA, look at its wiki. Does that mean, that the noises went away while PA was not active? That part is ambiguous, so please clarify.
You have several controls listed by amixer, that might cause trouble: Loopback Mixing, Auto-Mute Mode, Front Mic, Rear Mic and Line. Reduce those levels to 0 dB and disable loopback mixing and auto-mute:
amixer -c PCH set 'Loopback Mixing' Disabled
amixer -c PCH set 'Auto-Mute Mode' Disabled
amixer -c PCH set 'Front Mic' 0dB
# and so on Then there is the enable_msi parameter, if I recall correctly there was a thread were disabling or enabling it helped. See `dmesg | egrep -i 'hda|intel|msi'` and 'journalctl' for anything relevant to sound. What cpu is this? Intel perhaps? What governor is set for frequency scaling? Look at other module parameters, especially snoop.
The term weird is uninformative, unexpected is better.
Edit: You probably also should disable and unload suspend-on-idle-module from pulseaudio, this will prevent other applications from occupying alsa device, since PA will. Make sure pulseaudio-alsa package is installed, should you want to continue using PA. Alternatively use dmix and dsnoop as default sink and source, as stated on arch linuxs pulseaudio wiki page.
