Well, in a nutshell, the problem is that other than a simple beep I can't manage to get any sound out of the machine (2.2 kernels worked just fine) Ok, I'm lying already. gtcd will play a cd just fine. that's it. The mixer works, I can hear the volume change of the little clicks it gives me. Trying to start esd, I get about 1/2 way through the startup beeps and it hangs. (I have to then kill it off with gdb), but any other program (such as mpg123) simply generates no output whatsoever. With test11 it failed initializing the DMA, with test12 (from bk yesterday) it starts up same as it used to with 2.2 $ dmesg|grep ^DMA DMA sound driver installed, using 4 buffers of 32k. I've tried recompiling with various settings, etc. At best I get the same results. Switching back to 2.2, it works fine again. I'm using yaboot with no MacOS left to change anything with Mac. Using devfsd (stock install, all old compatible options, etc) After manually remaking sndstat $ cat /dev/sndstat PowerMac (AWACS rev 100) DMA sound driver: sound.format = 0x8 (unsigned 8 bit) sound.speed = 8000Hz (phys. 44100Hz) sound.stereo = 0x0 (mono) sq.block_size = 0 sq.max_count = 0 sq.max_active = 0 sq.count = 0 sq.rear_size = 0 sq.active = 0 sq.syncing = 0 And finally, if it's any help: [/proc/device-tree/pci/mac-io/davbus/sound]# for i in `dir`; do echo $i;cat -v $i;echo;echo "----";done #input-channels ^@^@^@^O ---- input-encoding-types 16bit-BE-signed-linear^@ ---- output-frame-rates ^@^@M-,D ---- #output-channels ^@^@^@^H ---- input-frame-rates ^@^@M-,D ---- sample-frame-size ^@^@^@ ---- compatible burgundy^@awacs^@^@ ---- model 343S0177^@ ---- sample-precisions ^@^@^@^P ---- device-id ^@^@^@^A ---- name sound^@ ---- sub-frame ^@^@^@^@ ---- device_type sound^@ ---- output-encoding-types 16bit-BE-signed-linear^@ ---- vendor-id ^@^@^Pk ---- Any help is much appreciated... anything else needed to know, just ask. -mike ** Sent via the linuxppc-dev mail list.
