When I watch movies in Smplayer there is a scratchy sound sometimes. All volume is on the 100% and I follow the guide on Scratching sounds in opensuse 11.1 - openSUSE Forums but nothing works.
If the volume is not on the 100 % I can’t hear anything or just very little.
I also makes the scratch sounds when I see movies on youtube or playing games,
Only the person who hears the actual audio can say “how much”.
Did you also go to YAST > HARDWARE > SOUND > OTHER > VOLUME and move both the PCM and Master (and speaker/surround if applicable) volume controls there up to a reasonable (but distortion avoiding) levels. Then close YaST. And then go to your mixer (kmix in kde and alsamixer/amixer in Gnome) and move the PCM, Master (and speaker/surrournd if applicable) to levels where the volume is ok and the distortion not present?
Too new ? I don’t know. How can I ? I do not know what hardware your 1.5 year old computer has. Nor do I know your PC’s software configuration.
You could run a diagnostic script that checks your PC’s hardware and software audio configuration, and then the script uploads a summary of the configuration to the internet and provides you a URL where the information is located. Thus you can then pass the URL to others who can check your configuration.
To run that script in openSUSE-11.1, with your PC connected to the Internet, type “su” to get root permissions (enter root password when promted) and type: /usr/sbin/alsa-info.sh
That will ask you if you wish to update the script. Select YES. The script will update.
Then run the script a second time: /usr/sbin/alsa-info.shand this time let the script complete properly. When it finishes it will give you a URL (where your PC’s configuration for audio is stored). You can then pass the URL to people who are trying to help you.
I note 126.96.36.199-0.1-pae kernel with a ‘Realtek ALC660-VD’ hardware audio codec.
You could try forcing alsa (upon booting) to a fixed configuration, instead of relying on the autoprobe of alsa to properly configure your hardware. You can do that by applying edits to your PC’s /etc/modprobe.d/sound file, selecting ONE AT A TIME items from this list from the HD-Audio-Models.txt files for alsa:
3stack-dig 3-jack with SPDIF OUT
6stack-dig 6-jack with SPDIF OUT
3stack-660 3-jack (for ALC660VD)
3stack-660-digout 3-jack with SPDIF OUT (for ALC660VD)
lenovo Lenovo 3000 C200
dallas Dallas laptops
hp HP TX1000
asus-v1s ASUS V1Sn
auto auto-config reading BIOS (default)
So lets say you start by trying “3stack” from that list. Then open your /etc/modprobe.d/sound file (with root permissions) and add this as the first line in that file:
options snd=hda-intel model=3stack
Note you can edit that file in gnome by typing
in gnome: gnomesu 'gedit /etc/modprobe.d/sound’
in kde: kdesu 'kwrite /etc/modprobe.d/sound’
entering root password when prompted for a password.
and then restart your alsa sound driver by typing **su -c ‘rcalsasound restart’ **and enter root password when prompted. Then start your mixer (kmix in kde and alsamixer/amixer in gnome) and test your sound. Be certain to apply all the techniques noted in this thread (such as YaST/mixer).
That may actually break your sound. No worries if it does, or if it does not help. In which case change “3stack” in the /etc/modprobe.d/sound file with “3stack-dig” and try again (restart alsa, restart mixer … ) … If “3stack-dig” fails, keep trying, one by one, going thru each item in the list.
Do any of those help improve your volume ? Note your mixer controls may change with different options, and that may make a difference.
