Funky GSM playback with Asterisk 1.2.1 (Load issues, maybe...)
Written by

Snaking,
Tuxedo.
I upgraded my Asterisk development machine to 1.2.1 a few days ago (from 1.0.something). Since then I've had really poor playback of the GSM sound files (slowed down dramatically, often dropping out) even to SIP phones connected across a local LAN. Connection and link to remote machines produces fine quality, so I'm assuming it's a ...
MythTV fixed (Missing kernel support for the OSS PCM API)
Written by

in
Tuxedo.
Turns out the MythTV failure was due to missing the OSS digital data interface in the Alsa module of the kernel (PCM), Myth was crashing in the middle of trying to work with the /dev/dsp interface without it. The card has again changed it's colour settings, but no big deal there.
Only major fallout still ...!-->!-->
Minor tweak to the kernel a bad idea (ztdummy non-functional, whole system gone for a bit...)
Written by

Woke up this morning to try the results of last night's last kernel recompile. I wasn't able to get zaptel running, and have been noticing that the system clock is going wildly out of sync (despite ntpd running), so I turned off the preemptive kernel switch. Oops. Every loadable kernel module became non-functional. Rebuilding the ...
Housekeeping is dangerous (Accidentally blow away my only working kernel's source directory...)
Written by

in
Tuxedo.
I ran out of disk space on my "old" drive (which is where my home directory and all non-multimedia files go), so I went through and killed off the various system directories from my old Linux install (I run from the new disk now). Unfortunately, I didn't remember that /usr/src contained the last working Kernel ...
Quick asterisk tips (Little things that kill ya...)
Written by

If you're seeing messages saying that asterisk was unable to open the sound device when running on a desktop machine, edit /etc/asterisk/modules.conf and tell it to use alsa instead of oss.
If asterisk is having problems finding a file, check to make sure that you haven't specified the file with spaces around it, that is ...!-->!-->
Getting MeetMe running on Gentoo (Key is apparently to specify the "zaptel" use flag when emerging)
Written by

in
Tuxedo.
I'm trying to do a little experiment with MeetMe under Asterisk. Nothing complex, just using a SIP account to create a little user's chat line thing. Eventually have it controlled by the provisioning system with a charge added to your monthly bill when you set up a conference.
I got blocked the last time I ...!-->!-->
Quick hint for running Gentoo stable (Without constantly having to upgrade...)
Written by

Tuxedo.
I realise this is probably covered somewhere in the documentation, but it's something I only figured out a few weeks ago, so here ya go:
When you want to merge an unstable package onto your Gentoo stable system, you often have to set unstable keywords on that package and half a dozen dependencies. Now, I've ...!-->!-->
Distractions, distractions (8+ hours into the working day without touching item 1 on the todo list...)

Today I was to rise, then work on the business plan. That was my entire todo list for the day. Instead I spent the bulk of the day on the VOIP project. There was a brief interlude where I provided free Unix lessons to one of our business partners.
Bit of time spent on learning ...!-->!-->
Distracted again (Setting up DVD player for Rosey's party)
Written by

Tuxedo.
I don't see any way in MythDVD to set the language for display. Since it's a French party, I imagine they'll want French for whatever DVD they choose. Sigh. Oh well, gmplayer it is. At least the video card is working with the DVD player again, was basically unusable before that.
nVidia finally runs (But no 3D accelleration)
Written by

in
Tuxedo.
Well, finally got the nVidia driver to work. Had to choose the nVidia AGP. Also had to explicitly specify the resolutions, I gather it was trying to choose too high a resolution and the monitor was just failing to display. Unfortunately, the 3D performance is pretty pitiful, maximum of 150fps and it slows down to ...
