[SOLVED] Crackling sound in Archlinux

Well I installed vlc and played some mp3 file and I noticed that there are some disturbances in playback , some crackling sound is coming during the playback and its not smooth..

[shashwat@myhost ~]$ lspci
[shashwat@myhost ~]$ lspci | grep Audio
00:14.2 Audio device: ATI Technologies Inc SBx00 Azalia (Intel HDA)
01:05.1 Audio device: ATI Technologies Inc RS880 Audio Device [Radeon HD 4200]
[shashwat@myhost ~]$ 

Here is the output of lsmod

[shashwat@myhost ~]$ lsmod | grep snd_hda
snd_hda_codec_hdmi     22378  1 
snd_hda_codec_via      52206  1 
snd_hda_intel          21738  8 
snd_hda_codec          73739  3 snd_hda_codec_hdmi,snd_hda_codec_via,snd_hda_intel
snd_hwdep               6134  1 snd_hda_codec
snd_pcm                71032  5 snd_hda_codec_hdmi,snd_hda_intel,snd_hda_codec
snd                    55132  21 snd_hda_codec_hdmi,snd_hda_codec_via,snd_hda_intel,snd_hda_codec,snd_hwdep,snd_pcm,snd_timer
snd_page_alloc          7017  2 snd_hda_intel,snd_pcm
[shashwat@myhost ~]$ 

is it due to the pulseaudio ? How am I suppose to fix it ?

Please do help

Thanks and regards

I've installed pavucontrol, and fiddled with configuration tab, specifically Internal Audio Profile. That seemed to help, although sometimes after logging into X, the sound is crackling for a first few seconds. Then it plays fine.

If you are running PulseAudio you could try some of the troubleshooting techniques suggested in the wiki:

turning  timer-based audio scheduling off worked for me when I was having similar issues.

Oh yes, I forgot, it did help in my case as well. Only sound in VLC while wacthing video became choppy...

So... I went with occasional crackling...

Re: [SOLVED] Crackling sound in Archlinux

Crackling could be caused by having the sound volume in alsamixer in the red zone. Try moving the bars to the yellow zone and turning your speakers up.
