The summary says it! The mixer is unavailable and the single master volume slider always returns to the bottom of its range (all the way off) when I try to move it up. Back versioning to gnome-media-2.4.1.1 partially solves the problem. The single master slider still won't move up, however the full mixer associated with gnome-volume-control comes up and works as expected, although I get the following warnings: Warning: This version of the Gnome Volume Control was compiled with OSS version 3.8.2, and your system is running version 3.8.16. Warning: This version of the Gnome Volume Control was compiled with OSS version 3.8.2, and your system is running version 3.8.16. Warning: This version of the Gnome Volume Control was compiled with OSS version 3.8.2, and your system is running version 16556.188.154. Other mixer apps such as gnome-alsamixer or the CLI alsamixer utility work properly, and sound otherwise seems to be working normally, except that nautilus now crashes when clicking on or mousing-over a sound file icon. I've googled a number of references to this problem, which otheres have had also, but found no solutions. # emerge info Portage 2.0.50-r8 (default-x86-1.4, gcc-3.3.3, glibc-2.3.3.20040420-r0, 2.4.20-gentoo-r9) ================================================================= System uname: 2.4.20-gentoo-r9 i686 Intel(R) Pentium(R) 4 CPU 2.60GHz Gentoo Base System version 1.4.16 ccache version 2.3 [enabled] Autoconf: sys-devel/autoconf-2.59-r3 Automake: sys-devel/automake-1.8.3 ACCEPT_KEYWORDS="x86" AUTOCLEAN="yes" CFLAGS="-O2 -mcpu=pentium4 -march=pentium4 -fprefetch-loop-arrays -pipe" CHOST="i686-pc-linux-gnu" COMPILER="gcc3" CONFIG_PROTECT="/etc /usr/X11R6/lib/X11/xkb /usr/kde/2/share/config /usr/kde/3.1/share/config /usr/kde/3.2/share/config /usr/kde/3/share/config /usr/lib/mozilla/defaults/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="-O2 -mcpu=pentium4 -march=pentium4 -fprefetch-loop-arrays -pipe" DISTDIR="/usr/portage/distfiles" FEATURES="autoaddcvs ccache sandbox" GENTOO_MIRRORS="ftp://gentoo.noved.org/ http://gentoo.noved.org/ ftp://ftp.ussg.iu.edu/pub/linux/gentoo" MAKEOPTS="-j3" PKGDIR="/usr/portage/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" PORTDIR_OVERLAY="/usr/local/portage" SYNC="rsync://rsync.gentoo.org/gentoo-portage" USE="X Xaw3d acl acpi alsa apache2 apm arts avi berkdb bindist bonobo cdr crypt cups curl doc dvd dvdr encode esd evo fastcgi flash foomaticdb gdbm gif gnome gpm gps gstreamer gtk gtk2 gtkhtml guile imap imlib ipv6 java jikes jpeg libg++ libwww mad maildir mcal mikmod motif mozilla mpeg mysql nas ncurses nls oggvorbis opengl oss pam pdflib perl plotutils png ppds python quicktime readline samba sasl scanner sdl slang slp snmp spell sse ssl svga tcltk tcpd tetex tiff truetype usb x86 xml xml2 xmms xosd xv zeo zlib" # uname -a Linux vishnu 2.4.20-gentoo-r9 #2 SMP Sun Feb 22 23:53:36 CST 2004 i686 Intel(R) Pentium(R) 4 CPU 2.60GHz GenuineIntel GNU/Linux
Restarting my session made the single applet volume slider work properly with gnome-media-2.4.1.1.
Updated gail, re-emerged gstreamer and reinstalled gnome-media 2.6.0. The problem seems to have gone away.
