My audio has been working for years. However after upgrading to 11.10 I get a constant hiss out of the speakers. I tried everything I can think of short of a fresh install. There seems to be a number of people with the same problem. If is all it would take to fix this is a new card I would do that but I dont know of a really compatiable sound card. apt-cache policy pkgname -> N: Unable to locate package pkgname My system is uses GeForce 9400 GT/PCIe/SSE2 and onboard audio. aplay --list-devices **** List of PLAYBACK Hardware Devices **** card 0: Intel [HDA Intel], device 0: ALC662 rev1 Analog [ALC662 rev1 Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: Intel [HDA Intel], device 1: ALC662 rev1 Digital [ALC662 rev1 Digital] Subdevices: 1/1 Subdevice #0: subdevice #0 Why aplay --list-devices gives two identical results is puzzling to me. Another strange thing that I found is alsamixer comes up for the most part garbled. I can email someone a screen shot if they like. What I can see from the the top of the AlsaMixer screen (coppied from the terminal): AlsaMixer v1.0.24.2 q�� Card: HDA Intel F1: Help �� Chip: Realtek ALC662 rev1 F2: System information �� View: F3:[Playback] F4: Capture F5: All F6: Select sound card �� Item: Master [dB gain: -15.00] Im sure that somewhere along the line it must be my fault but I dont know what else to do. The hiss is almost like listening to someone scratching a chalkboard; at least I can trun on the mute and it stops. The sound is present no matter what sould level I change it to. Another strange effect is that when I do adjust the sound level it goes through a series of up and down pitches. I can still hear audio play but it is overlayed by the hiss. I also tried moving my cables around (testing for interference) and tried diffrent headphones but they all produce the same effect. So please let me know what other information you might need.
