When hitting play near the beginning of a track, the track starts normally. When hitting it partway through the track (tested with OSS output plugin, too, and it doesn't do this) it starts over but the channels are reversed. And I thought I was going crazy not remembering which channel the intro solo in Ain't Talkin' 'Bout Love was on :/ Reproducible: Always Steps to Reproduce: 1. start playing song w/ alsa output plugin 2. press x near the beginning of the song -- playback restarts normally 3. press x a minute or so into the track, channels are reversed. gah! Actual Results: I thought I was going crazy. Expected Results: left = left, right = right ;) Portage 2.0.50-r8 (gcc34-amd64-2004.1, gcc-3.4.1, glibc-2.3.4.20040605-r0, 2.6.7-gentoo-r8) ================================================================= System uname: 2.6.7-gentoo-r8 x86_64 5 Gentoo Base System version 1.5.1 Autoconf: sys-devel/autoconf-2.59-r4 Automake: sys-devel/automake-1.8.5-r1 ACCEPT_KEYWORDS="amd64 ~amd64" AUTOCLEAN="yes" CFLAGS="-march=k8 -O2 -pipe" CHOST="x86_64-pc-linux-gnu" COMPILER="gcc3" CONFIG_PROTECT="/etc /usr/X11R6/lib/X11/xkb /usr/kde/2/share/config /usr/kde/3.2/share/config /usr/kde/3/share/config /usr/lib/mozilla/defaults/pref /usr/s hare/config /var/qmail/control" CONFIG_PROTECT_MASK="/etc/gconf /etc/terminfo /etc/env.d" CXXFLAGS="-march=k8 -O2 -pipe" DISTDIR="/usr/portage/distfiles" FEATURES="autoaddcvs ccache sandbox" GENTOO_MIRRORS="http://gentoo.oregonstate.edu http://distro.ibiblio.org/pub/Linux/distributions/gentoo" MAKEOPTS="-j2" 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 aac aim alsa amd64 apm avi berkdb cddb cdr crypt cups dvd dvdr encode fbcon flac foomaticdb gdbm gif gimpprint gpm gtk gtk2 imap imlib javascript jo ystick jpeg kerberos libg++ libwww mad mikmod motif mozilla mpeg ncurses nls oggvorbis opengl oss pam pdflib perl png python quicktime readline sdl slang s pell ssl tcpd threads tiff truetype xml2 xmms xv xvid zlib ~arch"
are other alsa applications affected by this channel reversal? What sound card do you have? Can you please test this with a vanilla xmms (disable the gentoo xmms patches to xmms by editing the ebuild).
commented out all epatch* lines in the ebuild (1.2.10-r5 btw, should have said before -- interestingly enough I was able to compile fine w/o the gcc3.4 patch -- running 3.4.1 now). did an emerge -v xmms, and the problem persists. sound stuff: -using 2.6.7-gentoo-r8 compiled-in snd_intel_8x0 driver -AMD8111 southbridge w/ Analog Devices AD1981B chip I'm not sure what else to test at the moment; it never does it when I just start a song, I have to hit play (or x) once it's already playing to reproduce this, so I'd [probably] need to find something that will let me quickly restart a stereo stream to ALSA -- suggestions?
note that many gcc 3.4 patches fix issues that only occur on x86
To make sure this is an xmms issue, can you try to produce this using zinf
broken zinf ebuild -- going to file that now and see if I can't work around it.
zinf does it too -- in fact the first time I played the track I've been using as a test, it started the opposite way from that in which xmms normally starts it. :/
just for completeness' sake, I went and tested with another MP3 (yeah, sloppy of me to have not done this before, but I've now confirmed that it happens with other tracks too).
alright, well it looks like it's probably a problem with your alsa drivers as I can't reproduce it with mine (emu10k1)... what version of the alsa drivers are you using? can you try a different version
Just had Q3 do it, and Q3 uses OSS, afaik, soooooo... sounds like a bug in this specific driver most likely?
yeah... it is almost definitely a problem with your drivers... do you have a gentoo-x86 install you can test so we can determine if it is amd64 specific? Either way, it's best to open up a bug report upstream on ALSA's website... let me know the bug number so I can track it.
unfortunately, no, and I don't have space until I get my replacement HDD back, which is now 3 weeks late :| and off to alsa-project I go.
