Add another finding here in case it is not mentioned before.
findings and investigation ==
You can enable audio on ubuntu lucid as follows:
1. Add USER ubuntu to audio group /* this seems has been fixed in the
latest Lucid */
# sudo usermod –aG audio ubuntu
2.
Li Li, it is unnecessary (and by and large incorrect; see bug 433654) to
add one's user(s) to the audio group when PA is used.
So, the question becomes whether there is a speex task in addition or
whether this issue is solely in the realm of compile-time for speex.
Certainly the 'trivial'

Another observation: If I delete .pulse from my home directory, i can
successfully run speaker test with both sampling rates and get sound out
of it. After rebooting though, it goes back to the way it was (48000
works, 44100 does not)

Eric, does aplay work for non-48000 Hz .wav files? I. e. is it a bug in
PulseAudio's resampling on ARM, or a bug in ALSA?
Luke, I seem to remember that pulse always drives the hardware alsa
device in the hardware-native frequency, and does the resampling itself.
I'm sure it's possible to find out
Martin, aplay works fine here with non-48000Hz .wav, at least for
8000Hz, 16000Hz and 48000Hz, not tried 44100Hz as I don't have any
sample wav here.

Paul can correct me if I misremember, but our conversation in #ubuntu-
bugs a couple/few weeks ago briefly was:
1) PA's configured sampling rate of 44100 Hz (in /etc/pulse/daemon.conf via the
default-sample-rate parameter) does not always match the input file's,
resulting in inaudible audio,
I changed default-sample-rate to 48000, logged out/in, and retested.
Everything still seemed the same though. 48kHz samples would play,
anything else would not.
I also tried this:
speaker-test -t sine -r 48000 - plays
speaker-test -t sine -r 44100 - doesn't play
If I run the same two commands
At this point we need straces.

Saeed,
speaker-test doesn't give me a sound here. There any switches to be

Luke, I've tried with rhythmbox, as well as other players and the result
is the same. I can play both wav and ogg/oga files as long as they are
48000 Hz rate, however files with other sampling rates such as 44100 Hz
don't seem to play - I just get silence.

If mplayer works on arm, try playing content via mplayer using the pulse

Hrm ok. My thinking is to try software that ony uses pulse to see if
that works. If different files with different sample rates play fine
through pulse, then its a gstreamer issue. If different sample rates do
not work, then its either pulse or alsa at fault.
Could you possibly go through
At a glance, this sounds like a gstreamer issue. COuld you try playing
some audio with rhythmbox and report back as to whether the sound plays?

could it be that we are missing the hardware specific codecs to drive

I've been looking into this more, and I don't think it's related to
totem. Using any sound player (totem, rhythmbox, even paplay), I can
play certain audio files, but not others, and it doesn't seem to be
restricted to just certain formats that will play either. The only
consistent thing I can
