Not only contrived, it makes little sense. First, something already exists for this called a mute button, or pause button. If you don't want other people to hear what's going on... why did you unplug your headphone? If I unplug my headphone while listening to music, it means I want to listen to it on the speaker.

Re: Alsa state chooser
WM8753.pdf pg 27: MICBIAS CURRENT DETECT The WM8753L includes a microphone bias current detect circuit which allows the user to set thresholds for the microphone bias current, above which an interrupt will be triggered. There are two separate interrupt bits, MICDET to allow the user to e.g. distinguish between one or two microphones connected to the WM8753L, and MICSHT to detect a shorted microphone (mic button press). The thresholds for the microphone bias current are set by MBTHRESH[2:0], for MICDET, and MBSCTHRESH[1:0] for MICSHT. Thresholds for each code are shown in Table 15. The circuit is enabled by setting MBCEN. See the GPIO and Interrupt Controller sections for details on the interrupt and status readback for the microphone bias current detect.

I wouldn't say never, but I really can't think of any pressing reasons to want to know when the state changes. Maybe it's just lack of imagination. And as for playing sounds off the message bus, why? Am I wrong for instinctively hating D-bus, and finding any reason to not use it? Or at least only using it for things that must be asynchronous? Something I could see as useful is a signal when headphones are plugged in. I remember reading in the Wolfson Codec manual that it is possible, by monitoring voltages or some such, I imagine that would have to be done in the alsa plugin or maybe in the driver though. -- View this message in context: http://n2.nabble.com/Alsa-state-chooser-tp224p2228688.html Sent from the Openmoko Community mailing list archive at Nabble.com. ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
Alsa state chooser
I'm not sure what the status of the Dbus sound stuff is, but I wrote a little program to choose the alsa state file with a simple gui. Attached is the code in anyone is interested. All it is is 1 button for each state file, very simplistic, uses elementary. (which btw kicks ass Raster) You would run it like so: scalpel `ls -1 /usr/share/openmoko/scenarios/` meh, whatever, works for me -Tim http://n2.nabble.com/file/n224/scalpel.c scalpel.c -- View this message in context: http://n2.nabble.com/Alsa-state-chooser-tp224p224.html Sent from the Openmoko Community mailing list archive at Nabble.com. ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

Re: voip on Debian
As of now, I'm using asterisk on debian to connect to an IAX2 provider. (diamoncard.us) There is a far end echo, that is being caused by asterisk on the Freerunner. Other than that, it is working perfectly. I don't know much about the FSO framework or zhone, but it would be trivial (from the asterisk end) to use zhone as the front end, as it would only take sending asterisk manager commands to control the console. Configuration of asterisk with a gui would be a sticking point, but not too complicated by any means. I'm still working on eliminating the echo, but I have a feeling that nothing short of a recompile will work (or a channel driver for the wolfson codec instead of using alsa, both of which I am ignorant about). I saw the asterisk .ipk in the community repo, does anyone know the source of that package, or who compiled it? -- View this message in context: http://n2.nabble.com/voip-on-Debian-tp842903p1132559.html Sent from the Openmoko Community mailing list archive at Nabble.com. ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
voip on Debian
I've had a lot of success running both twinkle and asterisk and I thought I'd share my experiences. Twinkle works well, but the gui is limiting on the touchscreen. I think once configured properly asterisk will make an excellent voip backend for the neo. You can control it through asterisk manager commands by writing text strings to a socket, and which has hooks for most languages I'm sure. The difficult part is getting a good set of configuration files for asterisk. I think for the most part I have a good setup for sip. iax could be configured too (important I think for the encryption). Heres the steps as well as I can remember: 1.) You need the alsa state for voip handset. Can be got here: http://svn.openmoko.org/trunk//src/target/audio/om-gta02/ This goes in /usr/share/openmoko/scenarios/ load it with the command : alsactl -f /usr/share/openmoko/scenarios/voip-handset.state restore 2.) Install asterisk, or twinkle, (or whatever, I got those two to work). In any program other than asterisk, you must enter your sip server info. For asterisk you need these changes: -modules.conf: change the sound module from oss to alsa (about halfway down) -alsa.conf: uncomment the audio devices and use `plughw` as the devices instead of `hw` like this "input_device=plughw:0,0" set autoanswer=no -sip.conf: you need to set your realm for your sip server set an outbound sip registration: register => user:[EMAIL PROTECTED] set authentication credentials for outgoing calls: auth=user:[EMAIL PROTECTED] I recommend using disallow=all & allow=ulaw or alaw, to avoid stressing the cpu, unless you have a slow net connection. -extensions.conf: you need to set up extensions to forward to your sip service exten => _1NXXNXX,1,Dial(SIP/[EMAIL PROTECTED]) It really helps to have an asterisk server that isn't NATed to test with If someone out there has the skills to make a gui, I can do the backend asterisk stuff. There is the potential to do some really cool stuff with asterisk it has quite a bit of functionality. -- View this message in context: http://n2.nabble.com/voip-on-Debian-tp842903p842903.html Sent from the Openmoko Community mailing list archive at Nabble.com. ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
