Low audio quality

#1 Post by sanjuro »

Hi,
i am trying Lucid Puppy 5.2.8 on my old laptop, but i have really low sound quality in vlc player comparing to sound quality in windows vlc. It sounds like there is some echo. I think there is some kind of realtek audio chip. Any general suggestions? thx.

Hi sanjuro

Welcome to the kennels 8)

Its possible you sound isn't configured or you need a different driver. Not heard of people experiencing echo.

the command

alsamixer

will set the sound levels and chose which card.

Have you tried you the ALSA sound wizard ( in setup menu )? Make a backup (while its not in use) of your save file first, or try without using savefile.

thanks for reply. i have tried it but nothing chnaged. There is a little echo, but the sound is so tinny. And sound is quieter than in win. This is only problem i need to solve because i really like puppy, really fast on old lenovo. Alsamixer says i have chip Realtek 861. Should i try official driver for linux os from their official sites or there is some community driver?

looking at the latest driver from Realtek looks like ALC861 is already included in ALSA under HD Audio codec.

what are the contains of /etc/modprobe.d/alsa-base.conf

and what is the output from aplay -l ?

(edit- are you using version 5 of 5.28 ? http://www.murga-linux.com/puppy/viewtopic.php?t=70855

according to https://bugs.launchpad.net/ubuntu/+sour ... bug/138322
adding either

options snd-hda-intel model=3stack

or

options snd-hda-intel model=auto

to

alsa-base.conf may work
