Re: [gentoo-user] What is the best audio system?

dmix *may* be able to handle multiple audio streams (in practice, in
my personal experience, it always requires more work than PA); but it

This seems like a dumb question (for I was a strict PA denier until recently
and have been using alsa-only since always), but does PA handle OSS
applications better than alsa/dmix? Whenever I want to use sidplay, which only
speaks OSS, I need to stop all other audio programs (e.g. press Stop in the
Clementine player if it's only paused), or else /dev/dsp was busy.
PA doesn't care about oss (/dev/dsp). It opens the soundcard through
normal alsa interface (which means /dev/dsp becomes busy). You can
either kill pulseaudio, or tell pulseaudio to suspend the correspondig
sink (not sure what exactly happens if an audio stream through PA is active
etc..).
Regarading oss (/dev/dsp) and plain alsa, it is the same, if something
opens the soundcard through alsa, /dev/dsp becomes busy... (even when
using dmix in alsa, because /dev/dsp is handled by a kernel modules,
dmix is userspace).
There is however a way to amke oss work with dmix through aoss (a small
program that preloads a binary, that 'hijacks' calls to open /dev/dsp
and 'reroutes' that to alsa, works most of the time, but can have
problems if the program does some weird things...)
In that case aoss opens the alsa device pcm.dsp (or dsp0, i'm not sure
right now), which you can easily point to dmix...
from my /etc/asond.conf:
pcm.dsp {
type plug
slave.pcm duplex
}
pcm.dsp0 {
type plug
slave.pcm duplex
}
pcm.!default {
type plug
slave.pcm duplex
}
pcm.duplex {
type asym
playback.pcm dmix:0
capture.pcm dsnoop:0
}
Then you can run (even multiple) 'aoss mpg123 file.mp3 ...'
You can also make this to work alongside pulseaudio, if you configure
pulseaudio to use the dmix device instead of directyly using the hw
device.
Nnote that this might cause problems, you have to disable pulseaudio's
autodetect and configure all soundcards manually, and using dmix
introduces some additional overhead and probles, also such setup is most
probably not supported by pulseaudio etc... However it also enables you
tu run plain alsa apps alongside PA (officialy you should just configure the
!default device to use the PA alsa plugin is simpler and it should work
better, though I had some problems with some apps) and more importantly
to run multi PAs simultaneusly (ie for multiple users...)

[gentoo-user] Freeing up disk space problem!!
Hi everyone, I'm experiencing a major problem right now. I've been using gentoo for several months now and I simply lllooove it! So here's the thing. When I use gentoo for a long time, even without updating the current pack of installed software (emerge -uD world), I am left without disk space... In situations like this I start deleting /var/tmp/*, /tmp/*, /usr/portage/distfiles/*, maybe do even a revdep-rebuild to fix something, but even then I'm left with no more then 100 mb, which obviously is not enough ... So this time I googled a bit and I deleted all the /usr/share/doc/ and this left me with 2.5 gb of space (wow). So the questions are ... in cases like this, what should be done? what is storing this much space? logs?

Also look at logrotate to help you automatically rotate, compress and delete old(er) log files.

I'll modify it as suggested. There is talk on the gentoo-dev list that mod-utils will be replaced by virtual/mod-utils which will default to kmod (required to build udev-181). Note that mod-utils and kmod are mutually exclusive. That should be taken care of in the ebuilds, but I'll monitor the situation. I may have to modify the setup instructions for conversion to mdev... i.e. an additional step, removing kmod and installing mod-utils. -- Walter Dnes waltd...@waltdnes.org

I know how to make LVM bigger but wanted to make sure this can be run even when there is data on there. Basically, can I run: tune2fs -m 1 /dev/data/data1 Which is where the ext4 file system is on the LVM. After I run that then I can expand LVM from there, I hope it works that easy.

Yeah, that makes sense, so why should the reserved setting affect fragmentation at all, unless you write so much data that the filesystem would be full with a larger m? In that case, I'd prefer fragmentation to a failed write. -- Neil Bothwick Don't just do something, sit there! signature.asc Description: PGP signature

A change of software might be considered later, right now I have to maintain a running server while moving to newer hardware and OS. Thanks, Stefan Stefan, I haven't had problems with upgrading, but I didn't wait this long. Eg. I didn't migrate from 2.1 to 2.4 directly. I would suggest you check on the cyrus-imap mailing list (see bottom of email) for tips. Installing it is simple, but there are a few changes with some of the files. A safer method would be running the 2 versions in parallel and using imapsync or something similar to copy the email over to the new version. -- Joost cyrus-imap list info: List-Id: Discussion group for Cyrus email system info-cyrus.lists.andrew.cmu.edu List-Unsubscribe: https://lists.andrew.cmu.edu/mailman/listinfo/info-cyrus, mailto:info-cyrus-requ...@lists.andrew.cmu.edu?subject=unsubscribe List-Archive: http://lists.andrew.cmu.edu/pipermail/info-cyrus List-Post: mailto:info-cy...@lists.andrew.cmu.edu List-Help: mailto:info-cyrus-requ...@lists.andrew.cmu.edu?subject=help List-Subscribe: https://lists.andrew.cmu.edu/mailman/listinfo/info-cyrus, mailto:info-cyrus-requ...@lists.andrew.cmu.edu?subject=subscribe
