Puppy barks, but when I come to play music the sound quality is wobbly and bad. Running Puppy 4.11 from a live Cd on HP compaq nc4010 laptop, 1,592MHz processor, 480Mb RAM. Alsa configurator identifies soundcard as ali5451. How can I improve the sound?

Thanks, Sarah

If by "bad" you mean distorted, try opening a console and type: alsamixer

Then check to make sure the levels aren't pegged 100%. Left/right arrow to toggle left/right on the GUI. Up/down arrow to raise/lower levels.

Master, Master M, and especially PCM are the ones to tweak.

If this solves your problem, open the console again and type: alsactl store

RSVP.

Laptops are also notorious for bleedover into integrated sound -mostly due to poor design but also due to failed components such as hard drives and fans - For this you could turn off unneeded components in your bios or remove unused components until it stops (no hard drive needed to run from live cd) - this is not a great solution but in a laptop if it is bleedover instead of clipping (what AJ was refering to) there is not much else you can do since rerouting cables is typically not an option in a laptop

Thanks for the replies. It isn't clipping, the sound is playing back at wavering speeds. Tweaking the alsamixer doesn't make any difference alas.

If you are playing audio CD's, run a cleaning CD in the drive a few times and also make sure the audio CD is clean and has no scratches on it.

Well, strangely enough I was able to play a DVD without sound problems. A CD sounded bad, as did a WAV file saved on my hard drive. Also get bad sound reproduction in TiMidity. The sound is fine in XP, and also good using a live version of Kubuntu, so I don't think there's a problem with the laptop. I'm a working musician - sound matters! I'd really like to be able to use Puppy - I'd be grateful for any help!

Sub_title: Sorted - using Retro Puppy instead
 

Well, I ditched version 4.11 in favour of the retro version - no more sound problems.

Now just have to set everything else up!
