Subject: alsa output started munging sound

Date: Tue, 6 Oct 2009 12:45:01 +0200

Package: audacious
Version: 2.1-1

Hi,

I ran into a bizarre problem with audio, and I didn't notice it until a few
hours of play :) audio output has been shifted a few notes down and slightly
slowed down, when played through the Audacious ALSA plugin. As soon as I
switch to the OSS output plugin, everything is back to normal.

To make sure it's not ALSA as a whole that's misbehaving, I've tried to
reproduce it with sox(1) (with libsox-fmt-oss and libsox-fmt-alsa), like
this:
% sox /win/WINDOWS/Media/tada.wav -t alsa default
% sox /win/WINDOWS/Media/tada.wav -t oss /dev/dsp
But both of those played the sound correctly -- the same at least, and the
same as the Audacious OSS output -- so I'm thinking Audacious ALSA plugin
is at fault.

I had previously fiddled with buffering settings (because the Audacious
version in lenny and with an older kernel used to skip a lot on this
machine under load), but I don't believe I selected any setting that would
need to cause this kind of distortion.

Hello Josip,

Audacious 2.2 will have a new ALSA output plugin.  Can you test it
please?  I've compiled a package which can coexist with the Debian
version.

(1) Download the .tar.gz and unpack it in the "/opt" folder, creating a
folder named "/opt/audacious".

        http://lockerbox.insideavemaria.org/Public/Students/john%20lindgren/audacious-unofficial-20091113.tar.gz

(2) Type this command to run it:

        export LD_LIBRARY_PATH=/opt/audacious/lib ; /opt/audacious/bin/audacious"
        
It's possible that the new plugin will fix your pitch problem; if not,
then we can debug it further.

Thanks for your time.

John Lindgren

Thanks for the offer, but I'm on x86_64 and your binaries are for x86_32;
I seemed to have most of the required libraries, but a couple are missing,
namely libmowgli.so.1, libmcs.so.1. I overrode those manually, but then
the plugins started complaining about libfaad.so.2, then I overrode that
manually, and then I got errors from them about libmad.so.0,
libsndfile.so.1, libvorbisfile.so.3, ... it's a new version of "DLL hell" :)
Sorry. Please provide a 64-bit build or tell us where to get the source.

I don't have a 64-bit machine around to build on -- the source is at
http://audacious-media-player.org .

Hello Josip,

Do you still see this problem with version 2.3?  You might also play
around with different sample rates; I once had a machine that would play
fine up to 48 kHz but would lower the pitch a little if I went to 96
kHz.

Peace,
John Lindgren

IMO 2.3 is more stable than 2.1, but of course it hasn't been tested as
thoroughly yet.

I'll need to fetch 2.3 from experimental, it seems. Do I need to expect
any flakiness because of this?

Just as I was about to upgrade to 2.3, I went to reproduce the problem, but
then I realized that I no longer have the same setup - that motherboard with
a NVidia CK804 broke a few weeks ago and I replaced it with a different one
that happens to have HDA ATI SB, so my ALSA now uses snd_hda_intel, and
I don't see any problem with Audacious ALSA plugin any more (v2.1).

JFTR this is on:

Since no one else stepped forward to corroborate my old problem, I'll close
this bug report, it could have been an obsolete fluke. Thanks for your
patience.
