**** BEGIN LOGGING AT Sun Jan 24 02:59:57 2010 Jan 24 11:39:44 so one would have to make alsa or pulseaudio read from this serial port to get whatever audio is put out there - same for recorded audio that has to be put in i guess Jan 24 13:24:50 josch: In case of the N900, yes. Unless Nokia publishes that PA changes. The kernel driver should be part of the OMAP tree. Jan 24 13:25:34 Other phones might just include a DSP or codec that manages the audio routing. For example the Openmoko phone has a codec for the routing details. Jan 24 13:25:52 meh then i have to motivate somebody to do so :/ Jan 24 13:26:05 yes Jan 24 13:26:14 i'm currently doing exactly that Jan 24 13:26:35 the wolfson chip is connected to the modem and routing is controlled by alsa switches Jan 24 13:26:56 so i currently write a deamon that controls the routing and volume without the need of statefiles Jan 24 13:27:17 but that is totally unrelated to my interest in the n900 :) Jan 24 13:29:57 The N900 works differently. And in the long term, all audio routing should be controlled by PA. Jan 24 13:30:19 PA is the only way to ensure a common base across different mobile phones. Jan 24 13:31:05 why is that? Jan 24 13:32:17 For phones like the N900 that handle the audio streams in the host. Jan 24 13:32:37 If you wanna mix in event sounds etc. Handle Bluetooth headset, then PA is the way to go. Jan 24 13:33:53 i guess i have to read in how pa handles devices that route in hw Jan 24 13:34:21 That is still work in progress I think. I know that I talked with Lennart about it. Not sure if he actually spent any time on it. Jan 24 13:37:12 or i dont read into that cause i got just reminded that pa takes 10% cpu there... Jan 24 13:38:06 it has a lot of audio enhancements, AGC, AEC, etc running in there too Jan 24 18:37:23 josh: pa can handle normal mixers, I'd be very interested if it can do asoc dapm type routing widgets Jan 24 18:37:43 and particularly if it can map them to outputs Jan 24 18:38:04 holtmann: even bluetooth pcm through hardware? Jan 24 18:38:41 our hardware does sco that way but a2dp over hci with highspeed serial port Jan 24 18:39:38 josch: freerunner uses analog for the modem not pcm, it has some issues that require a combination of hardware and software tricks to fix Jan 24 21:05:08 tmzt: I have the ofono packaging for maemo in gitorious, if you want to take a look Jan 24 21:05:51 tmzt: it only has the isimodem driver enabled, so you'd need to repackage for some other modem to work Jan 24 21:36:14 I don't mean changing the default, just including the other .so's but maybe they should be separate Jan 24 21:36:39 packages Jan 24 21:36:55 I think I can build on obs with that git **** ENDING LOGGING AT Mon Jan 25 02:59:56 2010
