Upgrading kernel from 2.6.14-r5 to 2.6.15-r1 --> 2.6.16-r1 causes mencoder to stop recording sound from bt878 tv card. Explicitly calling the alsa or oss device from the mencoder command makes no difference. All other sound, including sound playback from mplayer works fine. equery list mplayer [ Searching for package 'mplayer' in all categories among: ] * installed packages [I--] [ ] media-video/mplayer-1.0.20060302 (0) equery list gentoo-sources [ Searching for package 'gentoo-sources' in all categories among: ] * installed packages [I--] [M ] sys-kernel/gentoo-sources-2.6.14-r5 (2.6.14-r5) [I--] [ ] sys-kernel/gentoo-sources-2.6.15-r1 (2.6.15-r1) [I--] [M ] sys-kernel/gentoo-sources-2.6.16-r1 (2.6.16-r1) equery info Portage 2.0.54 (default-linux/x86/2005.0, gcc-3.4.5, glibc-2.3.5-r3, 2.6.14-gentoo-r5 i686) ================================================================= System uname: 2.6.14-gentoo-r5 i686 Intel(R) Pentium(R) 4 CPU 1.60GHz Gentoo Base System version 1.6.14 dev-lang/python: 2.4.2 sys-apps/sandbox: 1.2.12 sys-devel/autoconf: 2.13, 2.59-r7 sys-devel/automake: 1.4_p6, 1.5, 1.6.3, 1.7.9-r1, 1.8.5-r3, 1.9.6-r1 sys-devel/binutils: 2.16.1 sys-devel/libtool: 1.5.22 virtual/os-headers: 2.6.11-r2 ACCEPT_KEYWORDS="x86" AUTOCLEAN="yes" CBUILD="i686-pc-linux-gnu" CFLAGS="-march=pentium4 -O2 -pipe" CHOST="i686-pc-linux-gnu" CONFIG_PROTECT="/etc /usr/kde/2/share/config /usr/kde/3.4/env /usr/kde/3.4/share/config /usr/kde/3.4/shutdown /usr/kde/3/share/config /usr/lib/X11/xkb /usr/share/config /var/qmail/control" CONFIG_PROTECT_MASK="/etc/eselect/compiler /etc/gconf /etc/terminfo /etc/env.d" CXXFLAGS="-march=pentium4 -O2 -pipe" DISTDIR="/usr/portage/distfiles" FEATURES="autoconfig distlocks sandbox sfperms strict" GENTOO_MIRRORS="http://gentoo.mirrors.tds.net/gentoo ftp://mirror.usu.edu/mirrors/gentoo" MAKEOPTS="-j2" PKGDIR="/usr/portage/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" SYNC="rsync://rsync.gentoo.org/gentoo-portage" USE="x86 X a52 aac aalib acpi alsa apm arts audiofile avi bash-completion bitmap-fonts bzip2 cdparanoia cdr crypt cups curl directfb divx4linux dri dts dvb dvd dvdr dvdread edl eds emboss encode exif expat fam fbcon ffmpeg flac foomaticdb fortran gdbm gif gimpprint glut gpm gstreamer gtk gtk2 idn imagemagick imlib ipv6 isdnlog java joystick jpeg kde lcms libcaca libg++ libwww lzo mad maildir matroska mbox mikmod mjpeg mmx mmxext mng motif mp3 mpeg ncurses nls nocardbus ntpl nvidia ofx ogg oggvorbis openal opengl oss pam pcre pda pdflib perl png ppds pppd python qt quicktime readline recode rtc samba scanner sdl slang spell sqlite sse sse2 ssl svga tcltk tcpd theora tidy tiff truetype truetype-fonts type1-fonts udev unicode usb v4l v4l2 vorbis x264 xine xml1 xml2 xmms xv xvid zlib userland_GNU kernel_linux elibc_glibc" Unset: ASFLAGS, CTARGET, INSTALL_MASK, LANG, LC_ALL, LDFLAGS, LINGUAS, PORTDIR_OVERLAY

Alsa 1.0.10 won't work w/ 2.6.16 kernels. Reopen if latest alsa version doesn't work for you.
Upgraded alsa, but mencoder recording still broken: 2.6.14-r5 all sound works 2.6.15-r1 mencoder will not record sound (sound playback OK) 2.6.16-r1 mencoder will not record sound (sound playback OK) equery list alsa [ Searching for package 'alsa' in all categories among: ] * installed packages [I--] [ ] media-libs/alsa-lib-1.0.11_rc4 (0) [I--] [ ] media-plugins/xmms-alsa-1.2.10-r2 (0) [I--] [ ] media-sound/alsa-headers-1.0.11_rc4 (0) [I--] [ ] media-sound/alsa-tools-1.0.11_rc4 (0.9) [I--] [ ] media-sound/alsa-utils-1.0.11_rc4 (0.9)
try to configure mplayer properly the default device is wrong most cases now.
(In reply to comment #4) > try to configure mplayer properly the default device is wrong most cases now. On my system mencoder won't record at all if the wrong audio device is set. I have explicitly set the device (tried both /dev/dsp and alsa hardware device hw.0). Please see complete mencoder command below. Mencoder records video with 2.6.15 and 2.6.16, but doesn't record any audio and starts spitting out audio input error messages after a few seconds. #!/bin/bash #mencv4l2mpeg2 #tmpgenc matrix channel=${1:?"User--Channel Needed"} duration=${2:?"User--Duration Needed"} outputfilename=${3:?"User--Output Filename Needed"} #Remove leading "0" from channel if it exists #user input channel not needed with cable box -> s-video channel=${channel#0} #Remove file extension from outputfilename if it exists outputfilename=${outputfilename%.*} mencoder \ -tv driver=v4l2:input=0:normid=1:chanlist=us-cable:fps=30000/1001:\ amode=0:alsa:adevice=hw.0:audiorate=48000:saturation=20:brightness=0:\ contrast=-25:width=720:height=480 \ tv://$channel \ -vf crop=704:480:8:0,kerndeint,denoise3d=3:2:4,harddup \ -oac lavc \ -ovc lavc \ -lavcopts acodec=ac3:vcodec=mpeg2video:vqscale=4:\ me_range=8000:sc_threshold=100000:aspect=4/3:keyint=120:\ intra_matrix=\ 8,16,19,22,26,27,29,34,\ 16,16,22,24,27,29,34,37,\ 19,22,26,27,29,34,34,38,\ 22,22,26,27,29,34,37,40,\ 22,26,27,29,32,35,40,48,\ 26,27,29,32,35,40,48,58,\ 26,27,29,34,38,46,56,69,\ 27,29,35,38,46,56,69,83:\ inter_matrix=\ 16,17,18,19,20,21,22,23,\ 17,18,19,20,21,22,23,24,\ 18,19,20,21,22,23,24,25,\ 19,20,21,22,23,24,26,27,\ 20,21,22,23,25,26,27,28,\ 21,22,23,24,26,27,28,30,\ 22,23,24,26,27,28,30,31,\ 23,24,25,27,28,30,31,33 \ -endpos $duration \ -o "$outputfilename".avi
A google search turned up the following which may give additional info: http://www.ussg.iu.edu/hypermail/linux/kernel/0601.1/2754.html Seems I'm not the only one with this problem. Unfortunately, no solution that I could find.
Unmasking and installing mplayer-1.0.20060408 fixed the problem for me. Not sure whether to mark this as resolved, since the solution involves using a hard-masked version of mplayer.
closing since works for Sam, and pre8 is stable on his arch. :)
