Strange flash audio problems [Solved]

Postby eerok » Sun Jan 17, 2010 8:31

I've been having fun today playing with Sabayon for the first time. I guess from looking at my Gentoo forum account that I was using that in 2005, and today is likely the first time that I've emerged anything since then :)

I've solved many incidental problems along the way, but this one has stumped me: some .flv files have audio that is super speedy in VLC, sounding like violins on meth or something. Other .flv files are usually okay, but sometimes all of them are messed up and speedy. (In Dragonplayer, all .flv files seem to be messed up with nasty static noise.)

Audacity and Amarok and everything else I've noticed that gives sound seems perfectly fine aside from a little pop during startup. I'm using the Sabayon Christmas 5.1 Gaming DVD originally installed with Fluxbox, with gnome-light and kde-meta added. I'm using the KDE.

I've searched the forums and tried the fixes that I"ve found posted. The problem persists. Any ideas?

EDIT: I disabled pulseaudio by renaming it, and now just use alsa. Everything works for now, but I guess a pulseaudio update will break it again.

Hi, thanks for the info. Pulseaudio is still a pain sometimes. [for me, skype's microphone input is 'kinda' also]


I _guess_ there should be a cleaner way of disabling pulseaudio... Isn't there some guru here that could point us to the proper way to tell Sabayon to use alsa?

[and anyway, what component did you actually rename? Did you just try to uninstall pulseaudio?]

Cheers

A pulseaudio update won't be a problem so long as you follow some simple procedures when entropy pulls in the update.
I'm assuming you renamed the pulseaudio bin file, if this is the case then your procedure is quite simple.
1. Do all your updates via the command-line so you can see when a pulseaudio update is installed, let it install normally
2. After all the updates have been processed & installed & prior to a re-boot, do an " rm " on the old pulseaudio bin file you renamed.
3. then do the same " mv " on the new pulseaudio bin file that you did the first time, only after this will it be safe to shut down & or re-boot without loosing your current audio setup.

This way you will always have the latest pulseaudio on your system in the event that they actually get it to play nice with intel-hda.

Couldn't be simpler.

Sorry I'm so slow to answer, but I renamed /usr/bin/pulseaudio.

@catalyst:
Thanks for the info. Yes, I'm using an nvidia board with intel-hda.

Even with alsa I get some audio popping when an app that uses audio starts up. That's really the only annoying thing left.

You can also try this wiki post for HDA-intel.
http://wiki.sabayon.org/index.php?title ... ound_Cards

To determine your chipset model type the following in a terminal as root.
Code: Select all
cat /proc/asound/card0/codec#* | grep Codec

Then use the returned output to search for your model in the above wiki.

I've Gnome version of 5.1r1.
It's impossible to kill the pulseaudio process, by terminal (as root) and by System Monitor.
And, in fact,
Code: Select all
# rmmod snd-hda-intel
ERROR: Module snd_hda_intel is in use

Obvious answer is that pulseaudio is using hda-intel hence your module rm error pulseaudio must be killed first.
From your desktop hold down << ctrl >> key & tap << esc >> key.
In the system activity text box type " audio " without quotes then highlight each process using audio individualy & kill each one, you will not be able to kill hd-audio 0 as it is a module not a process so don't even try, then proceed back to the terminal & follow the wiki.
