I still can hear the noise too low but only when I increase the Volume of my speakers to maximum. I think that this is pretty normal. Thanks a lot, I really believed that there was a problem with my Debian Lenny. I didn't think that something so simple such as adjusting alsamixer would be the solution.

Sound card noise on Lenny amd64
Hi people: I have a Debian Lenny amd64 (up to date) running on a MSI K9A2 Neo2 mainboard. I have sound working without problems when suddenly some day started to sound badly: I hear a continuous noise like a 'shhh' (sorry if it seems funny but i don't know how to explain this). This noise happens always on Linux and I have tested against: - Rebooting - Disabling/enabling arts - Turning on/off aplications sound applications (amarok, kmix, kaffeine, etc) - Removing alsa-utils & alsa-base - Changing speakers and headsets I tought my sound card (integrated on the mainboard) got damaged so before asking for guarantee for my new PC I decided to install Microsoft Windows and discard problems. But surprisingly I noted that this noise isn't present at Windows platform where everything sounds fine, perfect. This extra information I got: - When increase os volume (with aumix) the noise get worse, like something burning up - When booting my Linux box (at some point of init scripts) the noise get started - When halting my Linux box (at some pooint of shutdown init scripts) the noise disappears - There's no noise at BIOS or GRUB booting time I think this is just a Linux problem. Does anybody has any idea? Thanks and sorry by my bad english -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
