The 2.6.37 kernel was just released and I immediately compiled and installed it. This is the plain vanilla kernel source which is the same as is available at kernel.org. Now, Alsa sound does not work. Everything on my system is the same except for the new kernel 2.6.37. The problem, as far as I can determine, is that the usual sound devices are not being detected. The Alsa sound modules load properly and my sound card appears in the list shown by lspci. But doing an strace with any of the Alsa utilities always shows the following: open("/dev/snd/controlC0", O_RDONLY|O_CLOEXEC) = -1 ENODEV (No such device) open("/dev/aloadC0", O_RDONLY|O_CLOEXEC) = -1 ENODEV (No such device) These devices do exist. I can reboot with kernel 2.6.36 and the sound works normally, but for some reason, the new kernel 2.6.37 modules cannot detect these devices. There are two sound "cards" available on my machine. One is the Intel HDA built into the motherboard (which I don't ordinarily use) and the other is a PCI M-Audio Delta 2496 (Alsa ice1712 driver). Alsa modules for both cards show the same failure, and both cards exhibit no problems with kernel 2.6.36. I already posted a report of this issue on the Alsa-users list but received no response. Before I go posting more reports I just want to ask for some confirmation. Has anyone installed the new 2.6.37 kernel and gotten functioning sound? Frank Peters
