Re-starting this thread with a modified title.. The results are the same with several versions of pulseaudio, including pulseaudio-1.0 pulseaudio -vvvv .... D: [pulseaudio] cli-command.c: Checking for existence of '/usr/local/lib/pulse-0.99/modules/module-udev-detect.so': success I: [pulseaudio] module-udev-detect.c: Found 0 cards. I: [pulseaudio] module.c: Loaded "module-udev-detect" (index: #4; argument: ""). This occurs on both a dell d430 and a macmini server. Using tinycorelinux with linux-2.6.33.3 glibc-2.11.1 and udev-151 the udev detection works. Using tinycorelinux with linux-3.0.3 with eglibc-2.13 and udev-151 the udev detection does not work I'm using the same config files and udev rules in both cases Is there any pulseaudio udev module or udevadm troubleshooting I can try?
