I use AC97 sound cards and they work fine. USB sound cards that adhere to the standard are supposed to work fine too, but I haven't experience with them either. Also, while I have pulseaudio installed, I have it disabled as the default device and don't start it on boot. So I can't help a lot with pulse stuff. There is a website, http://www.pulseaudio.org where you can probably get help. Others here might help you with pulse. The first suggestion is to go to the link below and run the shell script. It will print a whole bunch of information, much of it useful only for developers, but very comprehensive picture of your sound system. If you post it here, it allows people to see your sound setup, and perhaps spot a problem. You probably don't have any of the configuration from F10, but it would be great if you had run the alsa-info.sh program and saved the output so you could run it again and look at the differences. Good idea for next time. http://www.alsa-project.org/alsa-info.sh Run a wav file with aplay and see if it plays sound. aplay -D plughw:0,0 some.wav This will tell you if alsa has identified your device properly. Use something like audacity or amarok, which allows you to select the device to use, import an audio file, and see if it plays. Does the vu meter show sound while playing, even if it is silent? Try different outputs. What if you do the same thing after a pulseaudio --kill ? Have you run alsamixer to get the pulse volume control and turned it up? Go to the link below and download the latest driver snapshot. You can install it as it is supposed to be backward compatible, but that isn't necessary at this point. If you just unpack it, go into the directory that it unpacks to, something like alsa-driver-snapshot, and then into alsa-kernel/Documentation you will find all the driver documentation. Grep for your codec. Look at the HDA files for troubleshooting information. ftp://ftp.kernel.org/pub/linux/kernel/people/tiwai/snapshot/alsa-driver-snapshot.tar.gz I've had no major issues with sound in F11 x86_64, but I don't have hda-intel cards. I have pulseaudio installed, but don't use it. Before I disabled it, it seemed to work fine. -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
