As I see it, if I have to use ALSA's OSS-compatibility to get acceptable results, why not use the real thing instead? h,mm, lets see - because oss4 is broken by design? No it's not broken. It's awesome: http://insanecoding.blogspot.com/2009/06/state-of-sound-in-linux-not-so-sorry.html Also, what 'latency' are you talking about? Latency is the delay between giving the order to play a sound and the sound actually being played. It's usually around 30ms here with ALSA/dmix, and around 10ms with OSS/vmix. It's not funny trying to play something in a software synth with a keyboard when having a 30ms latency.

[gentoo-user] Emerge building a binary from installed package
Hi, I think there is a way to do this but it's not sticking out at me on the emerge man page. I'm doing a install and want to build a binary package from my running system and install it on the new install. Basically, I don't want to recompile, I just want emerge to copy the correct files and make a tarball for me. I found the buildpkg option but that seems to compile it first then make a tarball. Can I get it to skip the compile part? Is that a option that portage has? Thanks. Dale :-) :-)

[gentoo-user] Can't get PulseAudio to work
I decided to test PulseAudio on Gentoo since someone claimed the reason PulseAudio has a it blows chunks reputation because of Ubuntu shipping it with a broken configuration. So, I did: USE=alsa pulseaudio -oss emerge -auDNl --with-bdeps=y world This installed PulseAudio and rebuilt all applications to drop OSS support and use ALSA or Pulse instead. I also took a look at this: http://en.gentoo-wiki.com/wiki/PulseAudio and did the usermod -a -G plugdev pulse thing. I rebooted with an ALSA-enabled kernel and with OSSv4 completely removed. But it doesn't work; everything can use ALSA OK, but not PA. For example, mplayer -ao pulse video.mkv says: socket(): Address family not supported by protocol What now?

[gentoo-user] Webcam under linux-2.6.34.00
Hi, Recently I installed linux-2.6.34.00 (vanilla). I adopted the config file where (I thought) it need to. The previouse kernel I used was linux-2.6.32.13 (vanilla). With the old kernel I was able to use my Web Cam (Sony Playstation Eye/Omnivision ov534 according to usbview -- see below) via VLC media player 1.0.6 Goldeneye and via guvcview (I use a svn snapshot of this application). With the old kernel guvcview does not show any image control sliders but works fine so far. Using the new kernel, things are going wrong somehow When accessing the cam for the first time after a boot, there is often a video stream, but the image is much too bright. But guvcview offers image control sliders now even for my cam. But: Using that sliders or accessing the cam a second time after restarting as vlc as guvcview results in *nothing*: no stream, no picture. The real incarnation of a black whole. When starting guvcview from the command line it prints device temporarily not accessible/available or something like that. I haven't figured out whether the cam hangs or the driver goes nuts or... Powercycling of the Cam via usb unplugging/replugging does not help, though. I recompiled libv4l, guvcview and vlc when the new kernel was booted (and the /usr/src/linux symlink was set accordinglingly) but the result was the same. What can I do to access and use my webcam under linux-2.6.34.00 successfully? Below I included information about my system according the webcam: usbview -v: Bus 001 Device 003: ID 1415:2000 Nam Tai EE Products Ltd. or OmniVision Technologies, Inc.

Re: [gentoo-user] Preventing a shared interrupt
Does anyone know how to prevent my nouveau video card and ath wifi card from sharing interrupt 19? I can't move the video card slot and I'd rather not move the wifi card slot if possible. BTW, does anyone see any other opportunity for interrupt optimization here? I'm trying to optimize for video and especially audio, and I'm using a USB 1.0 sound card. # cat /proc/interrupts CPU0 0: 473139 IO-APIC-edge timer 1: 2 IO-APIC-edge i8042 7: 1 IO-APIC-edge 8:127 IO-APIC-edge rtc0 9: 0 IO-APIC-fasteoi acpi 12: 3 IO-APIC-edge i8042 14: 0 IO-APIC-edge ide0 19: 135597 IO-APIC-fasteoi nouveau, ath 20: 2 IO-APIC-fasteoi ehci_hcd:usb2 21: 13860 IO-APIC-fasteoi ehci_hcd:usb1 22: 971970 IO-APIC-fasteoi ohci_hcd:usb4 23: 3446 IO-APIC-fasteoi ohci_hcd:usb3 28: 21524 PCI-MSI-edge ahci FWIW a grep of the nouveau source doesnt bring up any hits on MSI, so it looks like the driver doesnt support it yet.

Well if I'm going to use ALSA I need something that gives me per-application volume control since ALSA is too broken to even provide that while the rest of the world moved on. oh yeah, one other thing: http://alsa.opensrc.org/index.php/Softvol ALSA CAN control the volume of every single app. You just choose to ignore it. Or you chose not to look for it. Either way, it is there. Without the inherent brokenness of OSS4 You live in your own little world, Armin. That has nothing to do with per-app volume. You're as ignorant as ever and I must ask myself why I choose to waste time talking with you, over and over again. This discussion is over. Welcome to my killfile. *plonk* Well, I'm not Armin but it does talk about per-app volume. This is a quote from the link above: Another usefull thing you can do is control the volume of every application seperatly, even if the application can't do it on its own.

[gentoo-user] spell checking using kile under gnome
I am using kile under gnome to edit latex files. Its ok, but I am having problems with the spell checker - it works and does the job except it cant add to dictionary so once I restart kile, I have to start again with every discrepancy picked up by the spell checker. I suspect its because of using it under gnome there is no way to set a personal dictionary. Ive installed kcontrol which is apparently what you use in KDE to set the dictionaries, but I cant see how to set a personal dictionary. Maybe I need to install/run a full kde to set it? - then will it stay set under gnome? Any help appreciated! BillK

Anyone have a clue what's going on? Why do you have -0 -- this replaces the \n's with a null character -- is that what you want? Not exactly. It doesn't replace anything. It tells xargs to look for a null to separate fields and to ignore the normal field separation characters. This is required if you have spaces in the field name, otherwise xargs sees the spaces as a field separator. xargs was doing exactly what I told it to do. Unfortunately, I didn't read the man pages and was relying on some poorly written web pages which indicated that -0 told xargs to skip spaces but didn't mention that it also told it to ignore \n. The solution, as Patrick Holthaus pointed out, was to use the -print0 argument with find, which instructs find to use the null character as a field separator in its output. -- The road of excess leads to the palace of wisdom. - William Blake

They recommend for users of 2D acceleration to put this in xorg.conf to get rid of the error message: Section ServerLayout Identifier X.org Configured Screen 0 Screen0 0 0 Option AIGLX false If you want to try 3D accel at your own risk, they say, you need to run their latest development libraries from git. I don't do that, so I don't know if the gentoo packages include that stuff. Maybe someone else knows? Thanks Walt. I don't need 3D so if that's what the error refers to I won't worry about it. The system is running great on Nouveau now. - Grant
Re: [gentoo-user] Preventing a shared interrupt
Does anyone know how to prevent my nouveau video card and ath wifi card from sharing interrupt 19? I can't move the video card slot and I'd rather not move the wifi card slot if possible. BTW, does anyone see any other opportunity for interrupt optimization here?

Oh wait, /var/log/ldaplog is my customisation of syslog-ng. But slapd messages should be written with facility local4. Trying it with the --debug option on the command line. The easiest way to find why your ldap server wont start is to run the command slapd -4 -d 256 which translates to run in ipv4 only with debug level of 256.

You might try reselecting java again: `eselect java-vm system 2` (for sun-jdk or whatever your choice is from `eselect java-vm list`) I don't think you need to use java-config directly anymore but I'm not sure. Eselect should create the symlinks for you. Or my lack of coffee might be showing.
