Sound doesnt work with "Realtek High Definition Audio" card

[Martin Olsson]

I just booted Gutsy Tribe 5 and the sound doesn't work. It didn't work before or anything though. Basically, if I double click "Experience Ubuntu.ogg" in the example files the video player will just shutdown automatically before any videos is shown (no error message). When I try the "Ubuntu sax.ogg" file it says it can`t be opened and it also says "No application suitable for automatic installation is available for handling this kind of file". No ogg player is started after this error and no sound is played.

After this I went into sound preferences and tried pressing "test" button for "sound events" using HDA Generic, and ALSA, and ESD and OSS. None of them work. Basically all of them exception ESD will showing a "Testing..." dialog but I hear no sound. With the ESD one I get a error message which says I should report a bug to GNOME (which I did). URL for gnome bug is here:
http://bugzilla.gnome.org/show_bug.cgi?id=472721

The error message I got when trying ESD as audio was the following:
audiotestsrc wave=sine freq=512 ! audioconvert ! audioresample !
gconfaudiosink: Internal GStreamer error: state change failed. Please file a
bug at http://bugzilla.gnome.org/enter_bug.cgi?product=GStreamer

In Windows Vista it says my sound card is "Realtek High Definition Audio". And it works in Windows so its not broken. The machine is a HP Pavilion 6525sc.

I`d be happy to post output from stuff like lspci or whatever, just ask for whatever you need below.

I just tried installing xmms and play an .ogg file. I can see the song title scroll by, the length of the song is correct and the seconds are ticking and even the equalizer is making waves. Basically, it looks like it's playing with mute but I have checked very carefully and I don't think it's in mute mode.

I've also tried downloading ALSA 1.0.14 (latest stable as of today), I compiled and installed it, reboot and still nothing (exact same symptoms).

I tried adding " options snd-hda-intel index=0 model=3stack" to /etc/modprobe.conf, and it worked. However, oonly the PC speakers worked and the headphone jacks did not work.

In addition, it stopped working again altogether after I installed some updates.

I have resolved this issue, using this post on the forums: http://ubuntuforums.org/showpost.php?p=3292524&postcount=158

It is important to have these dependencies before continuing:
debhelper
quilt
po-debconf

Follow those instructions, and it pretty much is the easiest, most pain-free solution to your problem.

see my comment, i got it to work.

I got sound now as well, but I used a slightly different approach. Thanks for the help though. Now it remains for Ubuntu devs to actually fix this bug and make Intel/Realtek sound work out of the box.

In 'hardy' my Realtak HDA-card doesn't work, although it did work with the previous version of Ubuntu.
