Multi-play problem of sound in pulseaudio

[mrcrazyani]

Hi, I've got some problem about between pulseaudio and soundcard, so I want to ask you how I can fix the problem.

My setting of computer is:

AMD Athlon64X2 5200+
ASUS M3A/H HDMI
2G DDR SDRAM
ATI 3870
MAYA 5.1 MK-II(Soundcard)

First, I didn't hear any sound in ubuntu, so I set all sound settings "ICEnsemble ICE1724 IEC1724 IEC958 (ALSA)" at "System - Preference - Sound, then problem occured.

My first problem is that I can't hear any sound in Youtube, and second is that I can hear only one sound of an application. For example, if I hear music in with rythembox, then I can't hear any sound with other application.

So I found solution first: http://ubuntuforums.org/showthread.php?t=789578

But I couldn't fix the problem.

I found that my problem correspond to:

The application does plays audio and does not list an entry in the Playback tab;
- the application is either accessing your sound card directly or playing sound via ALSA's dmix device. This will prevent PulseAudio from working correctly & cause audio mixing errors.

and

The application does not play audio and does list an entry in the Playback tab;
- the application is using PulseAudio but there is a problem, such as: a bug in PulseAudio, a problem with your ALSA kernel module or libraries, or your PCM/Master volume is muted.

First, If I set all settings of sound to ICEnsemble ICE1724 IEC1724 IEC958(ALSA), an application plays sound, but does not list an entry in the playback tab. Second, If I set all settings of sound to Autodetect, it does list an ectry in the playback tab, but I can't hear any sound.

So I checked all process, and I found it : $ alsamixer -Dhw

If I type that in terminal, then "HDA ATI HDMI" occurs. It is device of ASUS M3A/H HDMI, motherboard. I killed sound device of motherboard at Bios setting, but my default setting of sound device is "HDA ATI HDMI".

I don't know how to change the setting. And I can't confirm and fix contents of /proc/asound/. If I try, then I see only this :

Here are a few options to choose from from fixing pulse to disabling it and using asla, or replacing pulse with esound.

First fixing pulse

Disabling pulse and using alsa (Before deciding to remove pulse you should read the warning here as to what the result could be).
