2.5.48 and ALSA

Is it supposed to work when compiled into the kernel? I have it compiled with OSS emulation and it worked as modules with 2.5.47 but not compiled in to 2.5.48 (trying to avoid the whole modules changes here :)

I get the sound device recognised but I hear no output and aumix is only reporting Vol, Synth, Line, Mic and CD. No PCM. :/

This is the relevant part of dmesg. I can't give it in full because the buffer overflows on bootup. :/

I'd provide /proc/asound entries but there's a buttload of files there and I don't know what would be interesting. The only patch applied to the kernel is the one to make the kernel pnpbios option play nicely with my laptops broken bios (ie it lets me boot up).

Any question etc, please holler. :)

Works for me with snd-trident on 2.5.48 as modules.

Yes, it used to work. I have sometimes had to help the boot scripts as the "gave up" when modprobe failed. But it always worked after setting up the mixer manually.

Sometime before 2.5.47 ALSA broke, at least for trident. I haven't tested if it works with modules - if it don't work compiled-in it don't work for me. I don't get all the devices either.

Yes, and also avoiding the maintenance of modules.conf, extra devfs issues, and so on for only a little extra memory.

Remove this dummy driver, it does nothing.

Gah! I feel silly now. I had that when using modules so that things would stop complaining about not having audio when I didn't want it on (it usually brings down my laptop in a heap - instant off). Am trying now with the new ALSA drivers and 2.5.x to see if they do thesame or not. So far so good (ie no shutdowns). :)

BTW. Should having the Mic volume way-up result in a highly piched tone being emitted from the speakers? I don't remember this ever being the case before. (had this happen this morning when I turned the laptop on - nice way to -really- wake up)
