Re: [maemo-developers] Alsa on IT2006 beta
- can anyone offer insight as to why I can no-longer reflash the n770? Try to do it with flasher-2.0. You can find it in the same web page. Good luck! -- Jaime Ruiz Frontera ___ maemo-developers mailing list maemo-developers@maemo.org https://maemo.org/mailman/listinfo/maemo-developers

Was there really alsa to DSP audio driver in kernel in IT2005? I'll answer that question in a few hours when I rebuild the Maemo 1.1 scratchbox and try building and running aplayer. I've just reflashed to 1.1 (oh how I miss IT2006 already :)) and note that the /proc/ asounds directory has a subdir card0 with a symlink Dummy - card0. Inside card0 is a device file id which just returns dummy. So at this stage I'm not sure if that indicates there is or isn't an Alsa driver present. What I do know is that the documentation (http://www.maemo.org/ platform/docs/multimedia/multimedia_architecture.html) explicitly states that Alsa is supported and seems to discourage one from using ESD. I've looked into Gstreamer but quickly got bogged down in the complexity and it isn't obvious if it is even possible to get it working in the way I need (basically, playing midi notes - ideally with soundfont support) without developing a plugin. I could go down the SDL path as an alternative but given I use a library that supports Alsa (Fluidsynth) and the Maemo multimedia documentation says that it supports Alsa then I'm naive enough to believe it should be possible :) Don't get me wrong - I love the 770 and think that it is a great device. I'm just a bit frustrated at the moment with the quality of the available documentation (I can live with missing documentation, I find incorrect documentation a little harder to deal with). In any case, I appreciate your input. Steve ___ maemo-developers mailing list maemo-developers@maemo.org https://maemo.org/mailman/listinfo/maemo-developers
Re: [maemo-developers] Alsa on IT2006 beta
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Look for my earlier post to the list. Summary: the 770 kernel is linux-2.6.16-omap1 which does have generic ALSA, but not specific support for the 770. There was a patch posted to the linux-omap-open-source list which was supposed to enable the AIC23 ALSA driver for the 770. I buillt a kernel with that patch and installed it on my 770.I did get it to make sound, but it was not at the right speed, so I think the driver would need some work. As far I can tell, the 2.0 beta definitely does not provide ALSA support for the built-in sound. - -- Buck Steve Landers wrote: G'day, I'm currently porting a Fluidsynth based program to the n770 and notice that the Alsa driver appears to be missing from IT2006 beta. No big deal, except I can't seem to regress my n770 to the previous OS release - Nokia_770_SE2005_5_2006_13_7, which does have the Alsa drivers. When flashing I get a message Unsupported board (id = 0x) So, I have a few questions - are the plans for alsa support to be re-added to IT2006? - does anyone have the alsa driver built as a module that can be added to IT2006? - can anyone offer insight as to why I can no-longer reflash the n770?
