Sound quality horrible

I can confirm this.

I have the same kind of sound quality problem, but more related on the low volume for the microphone. It may be related to some extra gain control which is not available.

I can confirm... it sounds terrible. But on my other computer is sounds fine. It seems that my snd-hda-intel sound driver has the issue.
Further examination shows that if I record something with adacity it works fine. When I try to record again with one track already recorded that second one is very low soundings.
I can play an mp3 with totem-xine and record without issue. To me... it sounds like a full duplex sound issue.
I have regrettibly moved to skype for my conversations for the time being, until it gets fixed.
I can give you any information you need including a saved mp3 of my recording to show you what it sounds like.

This is probably the best description of at least what I hear...

Ironicly changing kernels fixed his problem. Don't know if we could do that here.

Might this be the same bug as http://bugzilla.gnome.org/show_bug.cgi?id=358338 That bug was fixed in Ekiga 2.0.4.

I have no problems with sound quality anymore (other than the standard VoIP artifacts)

Have also the same problem when using the ekiga packaged with feisty.

All sounds are normal, but when calling someone, the sound is choppy and mechanic.
(Using an nforce4 Motherborad with onboard sound, feisty64 on amd64)

I'm now using the ekiga repositories ( deb http://www.ekiga.org/admin/downloads/latest/ubuntu/feisty_amd64/ ./ ), which corrected the problem for me.

Does this fix your problem? It worked for me.

One more comment about that. skype stops working when you do this. you have to delete/move the script then start login again. Kind of a pain as it doesn't work with some games and does work with others.

The problem is still there in the Feisty packages, my problem was solved by using the Ekiga 2.0.9 packages from ekiga.org.

The ekiga-2.0.9 packages provided at ekiga.org fixed distorted sound for me (feisty).

These packages are drop-in replacements for the Ubuntu ones and I would suggest that an update to egika-2.0.9 would help many users.

I am going to close this because two people both say it's fixed with ekiga 2.0.9 which is included in gutsy. Unfortunately Ubuntu does not bump packages except with major problems. So your best bet to fix this is to upgrade to gutsy (when it's fully released).
