Quick reminder: I have 10 sound cards which need to have oss emulation enabled. However, I only see 8 devices (dsp-dsp7). Takashi suggested a patch to workaround this problem: http://mailman.alsa-project.org/pipermail/alsa-devel/2011-November/045764.ht... I've applied it to kernel 3.0.0 and the only result I get is message appearing in kernel logs: "unable to register OSS PCM device 8:0". I've done some debugging and the registration fails on these lines (sound/core/sound_oss.c): register1 = register_sound_special_device(f_ops, minor, carddev);

Try replacing 128 with 256 in register_sound_special_device() in sound/sound_core.c.
