Strange sounds with Headphones at PCI128
2003-03-04 03:12:34
Hi! My Sennheiser HD 570 are directly attached to my onboard SB PCI128 output on my Gigabyte GA-8IRXP motherboard running Windows 2000. This output seems to work OK if i connect it to my Pioneer Amplifier and then to either headphones or speakers - i cannot hear any artifacts, errors, shortcuts or other things ... it´s just a bit lower volume when i use the computer instead of a CD. But when i connect my Sennheiser directly to the soundcard, i get strange effects! Sometimes i think, that the headphones are broken - or will break on that - it just sounds like a crackling shortcut somewhere. Both the Sennheiser´s and the computer´s audio cable and connector seem to be OK, when i test this in different versions. Only headphones directly to soundcard just does not work ... I tried to check "digital output" for both of my CD-players in the computer - but i´m not sure about the effect. I just don´t know for what that setting is. Cannot find any documentation ... (Preferences, Systemcontrol, System, Sound and Multimedia, Hardware, then the CD-player, and then some panel about oter preferences). The tooltip there talks about digital output for some codecs, but those codecs are not shown and cannot be configured somewhere. So i dont know if this has something to do with my problem ... I checked, that Windows is set to Stereo Headphones when i test this - although no difference between 5.1 system and headhpones settings. Audio preferences for performance are on standard-settings ... Audio-output is always to Analog, not Autosense or Digital. I notice that the problems get less, when i close some of the audio drivers like CD, micro, modem, AUX, etc. in the Creative PCI Audio Mixer. Also, it get´s better, when i just use low-level volume of output - but that is too low-volume for me too hear. So, i´m in need of help Does anybody know what´s up with my computer? Does the SB PCI128 have problems? Does the Senneheiser just don´t work with that setup? Do i need other drivers or patches? Other ideas? Thanx for any input!!!
