ALSA works just fine by itself. ALSA has _never_ been the problem. There is no squal or high-pitched whine when running your test, and the test sounded exactly as it was supposed to.
Additionally, I can play music via ogg123 under pasuspender and directly to plughw:0 and the additional squealish, high-pitched sound is not emitted. However, then I only get to use 2 of my speakers, instead of all of them (5 speakers + LFE). If the sound is played through PA, it acquires a nasty high-pitched whining. ** Changed in: pulseaudio (Ubuntu) Status: Incomplete => New -- PulseAudio completely ruins all audio https://bugs.launchpad.net/bugs/455779 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
