Maemo normally uses a system-wide instance of ESD running as root. Maemo is intended for a PDA-like context where the person in physical possession is the authorized console user, and they tend to commingle system-level and userspace functions. It's a very different world from the usual desktop or server system, and IMHO there are advantages to the desktop way of doing things. One of the Nokia developers is working on getting PA and Bluez (A2DP) working, though I don't think he has officially stated for which OS he's doing this project. Apparently the differences between the ARM and Intel instruction sets make it hard to meet the desired CPU load goals due to optimization issues. Maybe he'll have comments. > > user$ pulseaudio > > W: core-util.c: setpriority(): Permission denied > > E: main.c: Failed to create '/tmp/pulse-user': Permission denied > > Can you create the folder /tmp/pulse-user yourself?

(not looked at the code > for a while so not 100% sure on that one). The filesystem for /tmp is tmpfs, and for the main flash disc is jffs2. But the expansion flash "discs" are typically vfat, hiss, boo. If /tmp/pulse-user had already been created as root, probably mode 700, that would explain the second "permission denied". Pick one style, remove the directory, and likely everything will be fine. > > If I run as root > > > > pulseaudio --system > > W: core-util.c: setpriority(): Permission denied > > E: main.c: Failed to create '/var/run/pulse': Permission denied /var/run is a symlink to /tmp/.run, root:root 755. If PA is configured to drop privileges, i.e. change to user "pulse", and this happens before the PID file is created, that would explain this error. Then again, it could also be a pre-existing PID file created as root. Have you added "user" to group pulse-rt in /etc/group? Although modern PA goes through PolicyKit to get realtime priority, I imagine it can fall back to the group method when PolicyKit is not available, as in Maemo-4.0. James F.
