Broken sound (only rattling sound)
I'm not able to find a thread that matches my problem. It must be a software/hardware bug, because sound works normally on a 2nd computer running the same Debian version (lenny), and it also work on the 1st computer running Debian (squeeze). - In fact the sound was working on the 1st computer in one installation of Debian lenny, but not on a 2nd (same) installation on the same computer. - Given that I had fiddled with its settings (for a different reason), and couln't fix it, I decided that the
software had now a bug, deleted everything on the partition and cloned the working Linux on it. It had the same problem, so old me thougth that I had a virus in the MBR and wrote zeros all over the H/D; I then checked that the MBR (512 bytes) consisted just of zeros, and reinstalled vista, Debian lenny and Debian squeeze on the totally clean drive.
The problem is still there also on a 2nd lenny installation that I tried, but squeeze works well.
It's possible that the lenny installation that was previously working, was doing so due to the magic of Debian-update, but I don't know.
The guilty computer is a Compaq SR5760AN (mobo pegatron violet M2N78-LA) with nVidia 0774 chipset and realtek HDA integrated audio.
If it's relevant, the DVD drive is HL-DT-ST DVD-RAM GH15L, video is Radeon HD3450, and CPU is AMD Phenom 9650 quad core.
If I use alsaconf, it comes up with 'snd-hda-intel' but there seem not to be any intel chip on the machine, and squeeze works and lenny DID also work.
Any good soul with a suggestion?
Thanks for your attention.
