hello again! it seem's that my problem is solved. gnubien from #alsa on freenode.org, told me that i should try to disable "PCI Dealy Transaction". until this moment i couldn't recogince any mistakes on the sound device. here i quote myself from the alsa wiki: "User comments Z421 wrote on 2007-02-20: /According to these sound glitches, i wan't you to say, that this was for me, on a m-audio1010lt, a problem in the bios. The option, which i had to disable, was "PCI Delay Transaction", to get this really disturbing glitches away. My mainboard is a asus a7v880, whith a via kt880/via vt8237. Also i often heard, that it is useful to set the "PCI Busmaster Waitstate" to a higher number than it is bios default. IRQ sharing is also sometimes a problem, and the "PCI Burst Mode" is also a good tip, but in my bios i don't have this option." / i hope, that now problem is solved now, and won't appear any more. best regards, harald gutmann Harald Gutmann schrieb: > hello! > > i've a soundcard with ice1712 chipset, but some time ago it started to > make troubles, but i couldn't figure out, why this problem appears. > when i boot my system, and play around with the sound, everything is okey. > > but when my system is running some time, i get crackling sound out from > the tweeters. > on the left output ports of my soundcard this problem is more, than on > the right side. > i get this crackling on every sound output application, i can hear it > when only listening music, > but really explicity i can hear it, when sending a sine signal through > my snd-card. > > i know, that this problem is bevore my amplifier, because when i change > the output's from the soundcard, the right side is crackling more than > the left. > > my alsa driver's are built from an 2.6.18 kernel, and everything from > the sound is in modules here. > also strange is, that when i reload the whole alsa part in the kernel, > sound works again, like when doing a fresh boot/reboot. > but after some time, the same problem starts again. > > does anyone of you have an idea, what the reason could be? > > > > best regards, > harald gutmann > > ------------------------------------------------------------------------- > Take Surveys.
