Greetings at all. I have this annoying problem, really annoying problem. Left speaker is crackling with some frequences.. it's quite unusable. It's documented almost everywhere. Known bug, indeed, but I haven't found a solution for it (yet, I hope). Through phones no problem. I tried almost everything: - alsa's ebuild - kernel from .26 (gentoo sources) through .28-r1 tuxonice (actual one) - model : intel-mac-v3, macbook, mbp3 - position_fix : 0,1,2,3 - probe_mask: 0,1 I can't find a solution, I need some help. If you need something more, ask me! Thanks. Reproducible: Always Actual Results: Left speaker produces an annoying crackling noise Expected Results: The sound should work well. elbryan@whitebox ~ $ emerge --info Portage 2.1.6.4 (default/linux/x86/2008.0/desktop, gcc-4.1.2, glibc-2.6.1-r0, 2.6.28-tuxonice-r1 i686) ================================================================= System uname: Linux-2.6.28-tuxonice-r1-i686-Intel-R-_Core-TM-2_Duo_CPU_T7300_@_2.00GHz-with-glibc2.0 Timestamp of tree: Fri, 23 Jan 2009 11:05:01 +0000 app-shells/bash: 3.2_p39 dev-java/java-config: 1.3.7-r1, 2.1.6-r1 dev-lang/python: 2.5.2-r7 dev-util/cmake: 2.4.6-r1 sys-apps/baselayout: 1.12.11.1 sys-apps/sandbox: 1.2.18.1-r2 sys-devel/autoconf: 2.13, 2.63 sys-devel/automake: 1.5, 1.7.9-r1, 1.8.5-r3, 1.9.6-r2, 1.10.2 sys-devel/binutils: 2.18-r3 sys-devel/gcc-config: 1.4.0-r4 sys-devel/libtool: 1.5.26 virtual/os-headers: 2.6.27-r2 ACCEPT_KEYWORDS="x86" CBUILD="i686-pc-linux-gnu" CFLAGS="-O2 -march=nocona -fomit-frame-pointer -pipe" CHOST="i686-pc-linux-gnu" CONFIG_PROTECT="/etc /usr/kde/3.5/env /usr/kde/3.5/share/config /usr/kde/3.5/shutdown /usr/share/config" CONFIG_PROTECT_MASK="/etc/ca-certificates.conf /etc/env.d /etc/env.d/java/ /etc/fonts/fonts.conf /etc/gconf /etc/revdep-rebuild /etc/terminfo /etc/texmf/web2c /etc/udev/rules.d" CXXFLAGS="-O2 -march=nocona -fomit-frame-pointer -pipe" DISTDIR="/usr/portage/distfiles" FEATURES="distlocks fixpackages parallel-fetch protect-owned sandbox sfperms strict unmerge-orphans userfetch" GENTOO_MIRRORS="http://distfiles.gentoo.org http://distro.ibiblio.org/pub/linux/distributions/gentoo" LANG="it_IT.UTF-8" LC_ALL="it_IT.UTF-8" LDFLAGS="-Wl,-O1" LINGUAS="it en" MAKEOPTS="-j4" PKGDIR="/usr/portage/packages" PORTAGE_RSYNC_OPTS="--recursive --links --safe-links --perms --times --compress --force --whole-file --delete --stats --timeout=180 --exclude=/distfiles --exclude=/local --exclude=/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" PORTDIR_OVERLAY="/usr/local/portage" SYNC="rsync://rsync.gentoo.org/gentoo-portage" USE="/ X acl acpi alsa berkdb bluetooth branding bzip2 cairo cdr cli cracklib crypt cups dbus dri dvd dvdr dvdread eds emboss encode esd evo firefox flac fortran gdbm gif gnome gpm gstreamer gtk hal hddtemp iconv imap ipod ipv6 isdnlog java jpeg kerberos libnotify lm_sensors mad midi mikmod mp3 mpeg mudflap ncurses nls nptl nptlonly nsplugin ogg opengl openmp pam pcre pdf perl png ppds pppd python qt3 qt3support qt4 quicktime readline reflection samba sdl session spell spl ssl startup-notification svg sysfs tcpd tiff truetype unicode usb vorbis win32codecs x86 xml xorg xulrunner xv zlib" ALSA_CARDS="hda-intel" ALSA_PCM_PLUGINS="adpcm alaw asym copy dmix dshare dsnoop empty extplug file hooks iec958 ioplug ladspa lfloat linear meter mmap_emul mulaw multi null plug rate route share shm softvol" APACHE2_MODULES="actions alias auth_basic authn_alias authn_anon authn_dbm authn_default authn_file authz_dbm authz_default authz_groupfile authz_host authz_owner authz_user autoindex cache dav dav_fs dav_lock deflate dir disk_cache env expires ext_filter file_cache filter headers include info log_config logio mem_cache mime mime_magic negotiation rewrite setenvif speling status unique_id userdir usertrack vhost_alias" ELIBC="glibc" INPUT_DEVICES="keyboard mouse synaptics evdev" KERNEL="linux" LCD_DEVICES="bayrad cfontz cfontz633 glk hd44780 lb216 lcdm001 mtxorb ncurses text" LINGUAS="it en" USERLAND="GNU" VIDEO_CARDS="intel vesa" Unset: CPPFLAGS, CTARGET, EMERGE_DEFAULT_OPTS, FFLAGS, INSTALL_MASK, PORTAGE_COMPRESS, PORTAGE_COMPRESS_FLAGS, PORTAGE_RSYNC_EXTRA_OPTS

Did your left speaker ever work properly with Linux? Does it work with Windows? Also, could we have a copy of your dmesg?
It seems like it affects >=linux-2.6.26, also not specific to TOI patches. Fabiano: is there a kernel version which works?
(In reply to comment #3) > Did your left speaker ever work properly with Linux? Does it work with Windows? > > Also, could we have a copy of your dmesg? > It never worked in Linux, never. And no.. I never get it to work with ever kernel I tried. Here comes the list: 2.6.25-gentoo-r7/ 2.6.26-tuxonice/ 2.6.25-gentoo-r8/ 2.6.26-tuxonice-mactel/ 2.6.28-tuxonice/ 2.6.25-tuxonice-r7/ 2.6.27-gentoo-r7/ 2.6.28-tuxonice-r1/ In OS X and Windows it plays wonderfully. Onestly, I didn't spend a lot of effort with kernels < 2.6.26 because I used them for a very short period. As you see above, I even tried mactel patches but they didn't help. I builded alsa with verbose debugging message..

Created attachment 179545 [details] Alsa kernel module configuration file These are the options I give to the kernel module. I'm quite confused about "modprobe.d/alsa" and "modules.d/alsa" configuration files. Which one should be used?
A Google search revealed many instances of this problem. As much as I hate pointing to Ubun^H^H^H^H^H Forums, I found many threads about it over there. Please, try some of the stuff that are mentioned in this thread: http://ubuntuforums.org/showthread.php?t=611345 Report back any progress. Thanks :)

A thing that I've ever noticed is that I haven't a surround control volume in alsamixer. I have PCM, Front, Line, Line-Boost, Line-Out, Mic, Mic-boost... Could this lack be related to my problem?
Can you reproduce this on the latest development kernel, currently 2.6.29-rc3?
Feel free to reopen with the requested test results from comment #10
