[linux-audio-user] quattro distortion under mandrake 9.0 - more details

hi all... firstly, please forgive me for crossposting - im trying to find the most appropriate list for the problems i've been experiencing with loud distorted noise running the usb quattro under mandrake 9.0.... i've ascertained now that it isnt a conflict with X, or with the mouse, as i booted into runlevel 3 and played a wav from the command line with exactly the same results. i had my doubts about this anyhow as i'm running this on a thinkpad 600e - it doesnt have much in the way of video acceleration from what i gather (NeoMagic 256 i think is the graphics chip).... i've been messing around adding and subtracting stuff from sysvinit and loading modules manually to see what might be conflicting, i've tried the mwave modem as well, as modems have often been the culprit for device conflicts, but this doesnt seem to make any difference. so far i've drawn a blank... it puzzles me, as i was happily running alsa for the usb quattro under mandrake 8.2 with no problems whatsoever. before i wipe everything (again!) and go back to 8.2 in desperation.... does anyone know of any issues or differences between sound under mdk 8.2 and 9.0? or any known issues with the quattro driver that might cause this kind of heavily distorted sound? i've checked it isnt a fault with my quattro as i ran it under windows (yuk!) and found that it ran fine. the only difference in my setup that might be worth noting is that under 8.2 i didnt realise that mandrake installed its own alsa - i grabbed a tarball from alsa-project.org and just installed it over the top and it seemed to work fine. with 9.0 i've decided to go with mandrake's alsa rpms, simply because i went through hell with conflicts between 9.0's rpms and the tarballs earlier... on this fresh install i kept things simple. maybe i should switch back to tarball? or maybe i should upgrade from the supplied alsa 0.9.rc2 ? were there changes in the way usb is treated in 9.0 as compared to 8.2 perhaps?... i can also get the distortion down to a listenable level - although still very much present - by playing mp3s in alsaplayer with the volume level down to 1%.... this is hardly satisfactory though and doesnt seem to work in any other apps (doesnt work at all under oss emulation)... sound level has always started out very loud with the quattro but never distorted like this... i've never had this problem at all until i installed mdk 9.0... any suggestions would be very gratefully received! thanks in advance, m~ -- iriXx www.iriXx.org copyleft: creativity, technology and freedom? info(a)copyleftmedia.org.uk www.copyleftmedia.org.uk _ ( ) ascii ribbon against html email X / \ cat /dev/sda1 > /dev/dsp *** stopping make sense ***
