Pulseaudio is a Bug

[smurf]

I have ubuntu 10.04 (AMD64), kernel 2.6.32-34.
In the last 15 days I found that Pulseaudio is not working as before. I have a TV card SAA7134, (since 3 years) that input the audio in line-in plug of the audio card. Suddenly has became mute, after surfing the web I found that I had to activate the loopback module, now is working. That is the first strange thing: suddenly loopback module has disappeared?
But now I have another problem: if I want to watch TV and listen it I have to select the line-in device in Pulseaudio preferences window, but in this way I can't use the mic with Skype and others chat software. To use the mic I have to go in the Pulseaudio preferences window and set the mic 1 option in the input device menu. Further, in this way I can constantly hear my voice in the speakers. That is annoying, Until 15 days ago (approx) ther was no need to make that choice, it was automatic.

How can I fix that ?

Thx so much.

To fix my problem I removed Pulseaudio and now my sound card is working like a charm.

Definitively Pulseaudio is a ballast for the pc and it doesn't give any advantage, only headaches.

I think that Ubuntu must left to the user the choice to use or not Pulseaudio, also some packages like indicator-sound and other releated should support the two systems.

There is no point to activate loop-back module, just make sure PA server don't touch "Line Playback Volume" and "Line Playback Switch" when you change the input profile

There is no delay when you are using the analog mixer of the codec.

That is the pòint!
You are speaking about a lot of things that are totally unknown to me.
To make simple and basic sound management with Pulseaudio a user has to be professional in sound engineering. WHY?
Alsa makes everything a user needs, without to be a sound engineer.

[Raymond (superquad-vortex2)]

Why do you choose the longest path which need CPU and add delay ?

Blue jack -> Analog Mixer -> Green Jack

Blue jack -> ADC -> Audio Controller -> PA loopback -> Audio Controller -> DAC -> Green Jack

The only solution to make microphone work is to install linux-backports-modules-alsa-generic...

Just go to:

Menu / System / Administration / Synaptic Package Manager

And search and mark for installation:

linux-backports-modules-alsa-generic

tip: if you have multiple versions click on the first and read the description which should inform what name to install...

If after the reboot and mic mute is off, still does not work, just go to terminal and type:

sudo nano /etc/modprobe.d/alsa-base.conf

and add or change the following:

options snd-hda-intel model=auto enable=yes

Then Ctrl+X, type Y to write and exit, reboot and mic will work.

Bye and have lots of fun with Ubuntu (the best).
