The kernel ALSAdriver as well as OSS emulation are activated, for the kernel config see below. alsaplayer -o alsa music.wav only produces white noise. Could this be a endianness-problem? I tried also alsaplayer -o jack music.wav and everything is ok. (jackd running at 44.1 kHz) Also, the ALSA output via aplay music.wav does not give any problem. All these obervations are reproducible on my iBook. I tried it with various wave files of different origin, to make sure that it is not an inconsistency in the wave file. relevant part of kernel-config: # # Advanced Linux Sound Architecture # CONFIG_SND=m CONFIG_SND_TIMER=m CONFIG_SND_PCM=m CONFIG_SND_RAWMIDI=m CONFIG_SND_SEQUENCER=m # CONFIG_SND_SEQ_DUMMY is not set CONFIG_SND_OSSEMUL=y CONFIG_SND_MIXER_OSS=m CONFIG_SND_PCM_OSS=m CONFIG_SND_SEQUENCER_OSS=y # CONFIG_SND_VERBOSE_PRINTK is not set # CONFIG_SND_DEBUG is not set # # Generic devices # CONFIG_SND_VIRMIDI=m # # ALSA PowerMac devices # CONFIG_SND_POWERMAC=m # emerge info Portage 2.0.51-r8 (default-ppc-2004.1, gcc-3.4.3, glibc-2.3.4.20041102-r0, 2.6.10 ppc) ================================================================= System uname: 2.6.10 ppc 750FX Gentoo Base System version 1.6.8 Python: dev-lang/python-2.2.2,dev-lang/python-2.3.4 [2.3.4 (#1, Sep 16 2004, 23:11:34)] distcc 2.18.3 powerpc-unknown-linux-gnu (protocols 1 and 2) (default port 3632)[disabled] dev-lang/python: 2.2.2, 2.3.4 sys-devel/autoconf: 2.13, 2.59-r6 sys-devel/automake: 1.8.5-r2, 1.5, 1.9.3, 1.6.3, 1.7.9, 1.4_p6 sys-devel/binutils: 2.15.90.0.3-r4 sys-devel/libtool: 1.5.10-r2 virtual/os-headers: 2.4.18-r2, 2.4.22 ACCEPT_KEYWORDS="ppc ~ppc" AUTOCLEAN="yes" CFLAGS="-O2 -pipe -mcpu=750 -fsigned-char -mpowerpc-gfxopt" CHOST="powerpc-unknown-linux-gnu" CONFIG_PROTECT="/etc /usr/kde/2/share/config /usr/kde/3.2/share/config /usr/kde/3.3/env /usr/kde/3.3/share/config /usr/kde/3.3/shutdown /usr/kde/3/share/config/usr/lib/X11/xkb /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 -pipe -mcpu=750 -fsigned-char -mpowerpc-gfxopt" DISTDIR="/usr/portage/distfiles" FEATURES="autoaddcvs ccache distlocks" GENTOO_MIRRORS="ftp://gentoo.inode.at/source/ ftp://linux.rz.ruhr-uni-bochum.de/gentoo-mirror/ http://gd.tuwien.ac.at/opsys/linux/gentoo/" LDFLAGS="" 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 aalib alsa apache2 apm arts audiofile berkdb bitmap-fonts blas bzlib caps cdparanoia crypt cups dba divx4linux doc dvd encode exif f77 flac font-server fortran gcj gd gdbm gif gnome-libs gphoto2 gpm gtk gtk2 guile icq imlib innodb jack jack-tmpfs java jpeg kde ladcca ladspa lcms libcaca libwww live lzo mad maildir matroska monkey motif mpeg mysql ncurses nls objc offensive oggvorbis opengloss pam pdflib perl png ppc python qt readline samba sasl sdl slang sndfile speex spell ssl tcltk tcpd tetex theora tiff truetype truetype-fonts type1-fonts usb wmf xine xml xml2 xmms xprint xv xvid xvmc zlib video_cards_radeon" pylon@gentoo.org 2005-01-09 01:14:58 0000 I know that ChrisWhite did some work on it.
