Do I get it correct: OSS works flawlessly under Debian, while installing ALSA breaks sound?

In Linux' menuconfig: OSS Mixer API x To compile this driver as a module, choose M here: the module x x will be called snd-mixer-oss. x x x x Symbol: SND_MIXER_OSS [=y] x x Prompt: OSS Mixer API x x Defined at sound/core/Kconfig:49 x x Depends on: !M68K && SOUND!=n && SND x x Location: x x -> Device Drivers x x -> Sound x x -> Advanced Linux Sound Architecture x x -> Advanced Linux Sound Architecture (SND [=y]) x x Selects: SND_OSSEMUL x More or less, if you compile your own Linux'es, this enables you to use ALSA without using ALSA-aware mixers. If this API emulation enabled you to change mixer volumes, the problem you have was limited to the ALSA mixer API (and the driver itself could be good enough). You could try it out. I really am running low on advises, though. Regards, Anders Breindahl.
