I'm having a problem with sound on my Fedora 9 box. I did a fresh install over F8, which worked fine.

The sound plays too fast. Just barely enough to notice. I timed a song that was supposed to take 3:15 to complete, but it did it in right about 3 minutes flat. I first noticed it when playing the Star Wars theme mp3, which I had naturally heard hundreds of times and it just sounded a little off. Of course it is annoying that my music is playing too fast, but xine can actually tell this and inserts a slight blank spot in the song every 3 - 5 seconds to compensate for this. It sounds like playing a really scratched up CD. When I play a song with verbose=9 in xine it gives me this every time there is a jump in the song (one line per jump):
audio_out: inserting 7535 0-frames to fill a gap of 15402 pts
audio_out: inserting 7562 0-frames to fill a gap of 15457 pts
audio_out: inserting 7545 0-frames to fill a gap of 15423 pts
audio_out: inserting 7539 0-frames to fill a gap of 15410 pts

But if I use an app that uses gstreamer it plays fast without the skipping.

Does anybody have a clue what would be causing this? Or even where I could begin to start diagnosing this?

It is very annoying and I will probably go back to Fedora 8 if I can't fix this (not that anybody really cares what I do).

I've been unable to debug the problem (nothing usefull in the logs) but indeed the sound is too fast!, in my case is really enough to notice.

mplayer doesn't have the problem so I switched to it, however, I prefer to use Amarok with the xine engine.

In fact something in xine is broken and I browsed too many hours already trying to find a way to detect the problem and fill a bug report.

This happens only in my work's PC, the one in my home is not presenting this behaviour.

I am experiencing the same audio problem after loading Fedora 9. There is a blank/skip every couple seconds when playing audio using Xine or VLC. However ,this blanking does not occur when playing the same audio using Mplayer, mpg123, Realplayer 11, and xmms, but the audio plays too fast. I did not experience this issue on any of the previous Fedora releases (Fedora 3 through 8). The problem seems to be associated with the sound driver in Fedora 9 for the Intel 82801 AC'97 integrated sound chip that is in my system. I have an external Sound Blaster MP3+ card which I tried (after disabling the Legacy sound chip in BIOS setup), and the audio plays correctly with no blanks/skips in Xine or VLC, and at the proper speed in Mplayer, mpg123, Realplayer 11, and xmms.

I have a integrated sound chip that I believe would be intel as well. I just decided to go back to Fedora 8. I use it for music and video too much for there to be any major issues. I'll just have to wait for Fedora 10. Unless I hear that the problem gets fixed later on, that is...

Yesterday, I found some a post about some issues on Dell computers related to the clock source and the tickless kernel mode.

I found the clock sources available with the command:
cat /sys/devices/system/clocksource/clocksource0/available_clocksource

And then changed the clock source on the fly with the command:
echo acpi_pm > /sys/devices/system/clocksource/clocksource0/current_clocksource

Nothing seemed to happen immediately but two or three hours later I opened Amarok and all the music started playing fine!!!.

Today I opened Amarok to play some music and found the problem again, even when I wrote clocksource=acpi_pm in grub.conf the day before.

So, I don't know if the clock source change did something yesterday to fix it or if something related to the updates applied during the day did the trick...

Anyway... it seems to be a there's a way to fix it.

look at creative cards I have never had issues with them in linux. the audigy se is the cheapest and is quite good $26.00... im using the audigy 2 zg

Hi there. Just registered to post the (my) solution, cause I was having the same problem.

I went to ALSA's official site and downloaded alsa-driver-1.0.17rc1, uncompressed it and made a simple ./configure, make and make install. The problemm, after a reboot, disapeared.

Hope it helps.

ok.. I am still relatively new and been self learning linux. i have 4 kids so expenses for buying a soundcard for pleasure just aint in the budget regardless of the price. i tried to muck my way thru this and research and am getting no where. im hoping someone here can help me try the fix that Sergio89 posted here.

when i try the ./configure this is what I am getting

It would be greatly appreciated if I get some help in breaking down what I need to do to get beyond this.

I believe it is telling you that you don't have the kernel source installed.

Follow this:

Ok update to this. I tried to follow the article you linked to. (I have used that setup as well when configuring other things as well as its a great help and I highly recommend everyone use the info there for reference) but it did not work for me. I got as far as downloading the source file but the install of it didnt work as outlined. I chalk it up to my inexperience with windows and building from source. Maybe one day I will learn it.

However by sheer chance I took a gamble and did a search to see if someone somewhere had already compiled an .rpm for the alsa-driver-1.0.17 for the .fc9.i386.rpm or .fc9.i686.rpm.

I hit on the following site...

http://atrpms.net/dist/f9/alsa-driver

I downloaded the
alsa-kmdl-2.6.25.10-86.fc9-1.0.17-68.fc9.i686.rpm first and installed with the command;

sudo rpm -Uvh alsa-kmdl-2.6.25.10-86.fc9-1.0.17-68.fc9.i686.rpm

as it is the dependency for the next file I downloaded
alsa-driver-1.0.17-68.fc9.i386.rpm

then installing that with

sudo rpm -Uvh alsa-driver-1.0.17-68.fc9.i386.rpm

once done I rebooted and it totally fixed my problem.

So I appreciate the information given. I wish I was as knowledgable as being able to do it the ways that were suggested, but hopefully in me posting this information someone else may have an easier time.

Cheers!
