Hi; Sound is a new baby to me. If I turn my speakers on I get horrible squawking and static that seems to shadow all my keystrokes etc. I have recently (yesterday) clean installed Fedora Core 4. The sound test during installation worked fine with only a very minor squawk. FC4 comes with the Alsa Mixer volume control for Ensoniq AudioPCI. Even when all the input/output lines including PC speaker and Line-in are turned off, my speakers continue to make noise. Only when the speaker power is turned off are they silent. I am using an ATI Wonder TV tuner that has never seemed to be properly connected to the sound i.e I can turn the TV off and continue to hear the audio part of the broadcast. I am not a cd (DVD), radio or music fan so I have little knowledge of where to start diagnosing the problem or how to solve it, and don't need an expensive sound system. However, here is a try for info but I am not sure what it means: " ~]$ cat /proc/asound/cards" 0 [AudioPCI ]: ENS1371 - Ensoniq AudioPCI Ensoniq AudioPCI ENS1371 at 0xdf00, irq 9 ~]$ cat /proc/modules | grep ^snd.* > soundproc.txt snd_ens1371 31649 2 -
