1 me4tw Member Registered: Posts: 3 PULSEAUDIO Crackling / Distortion This distortion is like a crackly echoey distortion. It actually has an echo component to it, When I change the output and it goes normal for a few seonds and tehre is a song playing, then it kicks in, the sound quality goes way down, it has this crackling sound, and very noticeable echo comes on the voices and the drums (which you can barely make out over the crackling). Output is perfect if forced to use ALSA directly, or if I boot into windows Seven. This is all pulse audio (probably the piece of crap. When I go pulseaudio -kill and then mplayer -ao alsa:device=hw=0.0 it plays perfectly without distortion. When I go alsamixer -c0 none of the sliders have any gain, they are all at 0db or -1db or so. To stop the distortion, chanigng from 44100 to 48000 and so on in the /etc/pulse/ whatever file doesnt work. What does work is opening pavucontrol and changing the internal audio on the configuration page. I hav a Barts thing that is turned off and an Internal Audio that can be set to a huge list of things like Analog Surround 5.0 Out, Analog Stereo Duplex, Analog Surround 7.1 Output + Analog Stereo Input, so on and so forth. Now changing from one to another will randomly make the distortion go away for 30 seconds, until I open a new program, close pavucontrol, or just wait a while, then it will come back on, and I'll have to change it to another, which won't work at first usually but randomly will. There is NO CORRELATION between what is actually chosen and what does and doesnt have distortion straight away. Basically Pulse Audio is $!+ all the sudden, and I don't know why. I have a fully updated system, hardware is as follows:$ lspci | grep udio Audio device: ATI Technologies Inc SBx00 Azalia ( Intel HDA) (rev 40) Audio device: ATI Technologies Inc.
Since my posting on the Sound MAX BSOD issues has become quite popular, I have decided to write another posting on my more recent experiences with the drivers in Windows XP. The problem was that it did not crash anymore but it did not let me record my cards output (which is called “ Stereo Mix” or also “ What You Hear” as a recording device). Here’s how to fix it. Disclaimer: I am writing this from memory as I did this some weeks ago. I cannot guarantee that this will work out, nor I can guarantee that this does no harm to your computer. I cannot be held responsible for any inconveniences, crashes or loss of data you may experience due to this instructions. The last driver I used was V but in the meantime a new version, namely V dated, became available for download at the ASUS ftp site. In the extracted archive, there’s a file which contains all the information required to install and setup the driver files and I found several entries which explicitly disabled the Stereo Mix for whatever reason. I changed all of them and installed the driver, and this is what I got: Here’s a step by step guide to help you making the necessary changes. Modify the installation package Download and the archive from here and extract it to an empty directory. Open the file W1254624 J_ XP32 SMAXWDMW2 K_ XPADIHd Aud.inf in a text editor, e.g. Notepad. Go to line 1322 (or search for “ Disable Stereo Mixer”) and change the following line HKR, AD1986\ Disable, Out R, 1, 01 ; Disable Stereo Mixer to HKR, AD1986\ Disable, Out R, 1, 00 ; Enable Stereo Mixer Do the same at line 1355 (or continue searching for “ Disable Stereo Mixer”) Save the edited file. Install the driver Installing is a bit more complicated. First of all, you will need administrator privileges in order to install the driver. Moreover, note that I’m using a German Windows XP installation and I don’t know the.
