Sound stutters

[stephanelefou]

Hi,

Sound/music playback on my system is stuttering. I tried everything I've been able to find on the Internet about my hardware, Alsa and PulseAudio. Nothing works. I tried 9.04, 9.10, PuppyLinux, FreeBSD, in all cases, sound is stuttering. Under Windows everything is fine, but I want to turn this box into Ubuntu and sound is the only issue I'm having.

Box description:
Dell Gx150 (mini desktop)
1Ghz CPU, 1GB Ram
Audio type Sound Blaster emulation
Audio controller Analog Devices AD1885 AC97 Codec

None of the proposed fixes did work in my previous thread on the same topic:

Box specs:

There must be a way... :s
Thanks.

I did try this:

and no more sound now. :confused:

First remove the problematic packages with this command.

sudo apt-get --purge remove linux-sound-base alsa-base alsa-utils



Then log out and log back in.

Then reinstall the packages with this.

sudo apt-get install linux-sound-base alsa-base alsa-utilsSee if you have sound again.

No luck. When the system starts, it says that Pulseaudio failed, falling back to. "" I would expect the SoundCard name here but it falls back to nothing. I don't have anything in kMix either.

Will try openSUSE and see.
Thanks.

If it is a problem with pulse you can try removing it and see if that helps.

sudo apt-get remove --purge pulseaudio

[stephanelefou]

I tried that before. I don't have any sound hardware showing up anymore.

[stephanelefou]

Wow, I meant: MCNLive, not openSUSE.

Everything works just well, very small distro :)
yeah :p

You want to keep working on the sound in Ubuntu or are you switching?

This workaround did work for me on Mandriva 2010 (using ac97_clock=42000)

Will try it on Ubuntu soon and let you know.

Ok, back with the Ubuntu 9.10 image. Hum... modprobe.conf does not exists but I think it's rather in: /etc/modprobe.d, under alsa-base.conf. Typing: "sudo cat * grep | intel8" shows that my soundcard is somehow "blacklisted" :confused:

Don't know what to do to change. Will try to put:
"options snd-intel8x0 ac97_clock=42000" as a parameter and hope. Otherwise, I'll revert back to Mandriva where it works.

Suggestions are welcome.

Look in /etc/modprobe.d/blacklist to see if its blacklisted.

[stephanelefou]

Yes, it is in the blacklist, that's what I was trying to say in my last message.

Is there's anything I can do about it? Can it be "un-blacklisted"?

Thanks.

[RedSingularity]

Yeah, just delete it from that file.
