Pulseaudio depends on libatomic_ops. However, libatomic_ops don't have support for mips. I've created a patch for mips, though only work on 32bit userland. Get it here . Pulseaudio now compiled and installed on my loongson box. Can't use it to play though. The following is some detailed info, if you are interested in. My setup is to use alsa's pulse plugin. I tried aplay, for example: $ aplay /usr/share/sounds/alsa/Front_Right.wav aplay: pulsecore/mutex-posix.c:75: pa_mutex_lock: Assertion `_r == 0' failed. Aborted Before this assertion failed, aplay is stuck on a futex system call. connect(7, {sa_family=AF_FILE, path="/var/run/pulse/native"}, 110) = 0 send(6, "W", 1, MSG_NOSIGNAL) = -1 ENOTSOCK (Socket operation on non-socket) write(6, "W", 1) = 1 gettimeofday({1187375795, 973686}, NULL) = 0 write(6, "W", 1) = 1 futex(0x45dd1c, FUTEX_WAIT, 1, NULL
