Output is ALSA. If I play the same using mp123 or mpg321, the sound is clean. The distortion makes the sound quite unintelligible and is like if 50Hz transformer stastion sound with heavy sparking and arcing was sounding into the sound quite loudly (but it goes from the sound it's distortion of the sound it's not independently intermixing into). The XMMS is total crap anyway. Other tracks skip randomly forward etc. Reproducible: Always Steps to Reproduce: 1. 2. 3. 2-gentoo-r10 i686) ================================================================= System uname: 2.6.12-gentoo-r10 i686 Intel(R) Pentium(R) M processor 1.50GHz Gentoo Base System version 1.6.13 dev-lang/python: 2.3.5-r2 sys-apps/sandbox: 1.2.12 sys-devel/autoconf: 2.13, 2.59-r6 sys-devel/automake: 1.4_p6, 1.5, 1.6.3, 1.7.9-r1, 1.8.5-r3, 1.9.6 sys-devel/binutils: 2.15.92.0.2-r10 sys-devel/libtool: 1.5.18-r1 virtual/os-headers: 2.6.11-r2 ACCEPT_KEYWORDS="x86" AUTOCLEAN="yes" CBUILD="i686-pc-linux-gnu" CFLAGS="-O2 -mcpu=i686 -pipe" CHOST="i686-pc-linux-gnu" CONFIG_PROTECT="/etc /usr/kde/2/share/config /usr/kde/3.3/env /usr/kde/3.3/share /config /usr/kde/3.3/shutdown /usr/kde/3.4/env /usr/kde/3.4/share/config /usr/kd e/3.4/shutdown /usr/kde/3/share/config /usr/lib/X11/xkb /usr/lib/mozilla/default s/pref /usr/share/config /usr/share/texmf/dvipdfm/config/ /usr/share/texmf/dvips /config/ /usr/share/texmf/tex/generic/config/ /usr/share/texmf/tex/platex/config / /usr/share/texmf/xdvi/ /var/qmail/control" CONFIG_PROTECT_MASK="/etc/gconf /etc/terminfo /etc/env.d" CXXFLAGS="" DISTDIR="/usr/portage/distfiles" FEATURES="autoconfig distlocks sandbox sfperms strict" GENTOO_MIRRORS="http://distfiles.gentoo.org http://distro.ibiblio.org/pub/Linux/ distributions/gentoo" LC_ALL="en_US.UTF-8" MAKEOPTS="-j2" PKGDIR="/usr/portage/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" SYNC="rsync://rsync.gentoo.org/gentoo-portage" USE="x86 X aac aalib alsa apm arts avi berkdb bitmap-fonts cdr crypt cups curl d ga divx4linux dri dv dvd dvdread eds emboss encode esd exif fam ffmpeg fftw flac flash foomatic foomaticdb fortran ftp gd gdbm gif glut gnome gpm gstreamer gtk gtk2 guile icq imagemagick imap imlib ipv6 jabber jack java javascript jpeg kde ldap libcaca libg++ libwww live matroska mikmod ming mmap mmx mng motif mozilla mp3 mpeg mysql nas ncurses nls ogg oggvorbis opengl oss pam pdflib perl php png python qt quicktime readline real ruby samba sdl sharedmem shorten slang socks5 speex spell sse ssl svg svga tcltk tcpd tetex theora threads tiff tls truetype t ruetype-fonts type1-fonts unicode vorbis wifi win32codecs wmf xine xinerama xml xml2 xmms xpm xv xvid zlib userland_GNU kernel_linux elibc_glibc" Unset: ASFLAGS, CTARGET, LANG, LDFLAGS, LINGUAS, PORTDIR_OVERLAY
Well, best bet - don't use it. :=)
Actually I forgot to attach the original mp3. Sorry. I am also attaching another one I found which has the problem. Common to both is that they are mono and 64kbit/s.

I have another mono mp3 which is 128kbps and doesn't have the problem. One of the attached mp3s is 32kHz sample rate and the other 44.1kHz. Therefore the problematic combination seems to be mono+64kbps without regard to sample rate. Both play OK in mpg321. So I think it's XMMS or some underlying library has buggy handling of MPEG frame headers. Sorry BRI is not Bass Research Institute but Bassline Research Institute.
The distortion disappears when I set volume to 100%. If I set it to lower values (like 12%) it becomes distinctively audible. Alsa 1.2.10 output plugin, use software volume control on, mixer device PCM, multi thread mode, mmap mode. Problem manifests only when I leave the audio device to default. When I switch to hw 0,0 then it goes away. I have found another mp3, this time mono but 192kbps which does it! Samplerate is 44.1kHz
I couldn't attach the file. Here is URL: http://www.scene.org/file_dl.php?url=ftp://ftp.se.scene.org/pub/demos/scene.org/music/groups/8bitpeoples/8bp044-01-goto80-ter4.mp3&id=290533
well atm i don't know how to deal with this bug. It's probably better for you using another application do deal with this files. Reopen if you got a patch for this.
