Try to test[1] on www/linux-firefox to verify if this a platform
specific bug.

In my case on Nightly after pause takes effect (a few *seconds* after
hitting it) firefox cpu usage ramps up to 100% in audio_callback around
pthread_mutex_unlock, i.e. sydney_audio_oss.c:459. And if I close the
tab while sound still plays (whether or not I hit pause) the bug would
not appear.

[1] if you manage to make sound work (I haven't) despite linux aplay(1) working fine;
    a few related diffs attached, may or may not make a difference
