Nice, imo that's the way how it should work. Alsa states were easiest solution - that's why i used it. Your code could work much better. You can see that change at https://github.com/neiljerram/qtmoko/commit/f8a040e352bf6158baa508b1d7bfdb7e42aa32d0, and if you like try it out on your A4 too. It works nicely for me on A3. For A4 I've added code to set the 'Voice route' control correctly, which should be equivalent to your recent 5mA saving change (84fb56e), but I don't know if I've got it exactly right because that code isn't executed on my A3. Also for A4 it might be necessary to switch the 'Codec Operation Mode' control between 'Option 1 (audio)' and 'Option 2 (voice/audio)', but I haven't written any code for that yet, because - the last email discussion about that didn't seem completely definitive about whether it is really needed - the Phone*.state files in devices/gta04/src/plugins/audiohardware/neo/a4 were inconsistent on this point, i.e. PhoneEarpiece.state had 'Option 2 (voice/audio)' but PhoneSpeaker.state and PhoneHeadset.state had 'Option 1 (audio)' - if we _do_ need to switch 'Codec Operation Mode', we probably need to do that inside pasuspender, so that would make it a bit trickier than the other controls. Therefore it would be nice to know if my change works on A4. One detail, which is nice but slightly worrying, is that I used to always to get a very audible click about 1s before, e.g., hearing the new message arrival sound; and with the reimplementation I no longer get that click. I _think_ the explanation for that was using pasuspender, and that I no longer get it because I no longer need to use pasuspender pasuspender will still have to be used on A4 when switching to earpiece, because you cant switch if some other program has sound card open. Do you mean the switching of 'Codec Operation Mode' here? Is that actually needed for earpiece but not for speaker or headset? If so that would explain what I've described above as inconsistent. - but it's slightly worrying in case that's wrong, and in particular in case it's because I'm leaving some circuit on more than before, and hence drawing more current. (I haven't seen any evidence for drawing extra current.) Maybe it can be measured during suspend. Since having this change in place, I've been seeing the same average suspend currents as before.

Re: QtMoko audio state work
I wanted to write a bit of an update on my recent GTA04/QtMoko work, and would appreciate people's thoughts. This is still focussed on audio handling, because with my A3 I still haven't reached a point of having fully reliable phone calls. (As usual, for the sake of avoiding any possible negative marketing, I should point out that the main problems here are A3-specific. I hope, and believe to be the case, that phone calls are already reliable on A4.) With Neil Brown's helpful input, I've reviewed and improved my understanding of all the ALSA state files and controls.

I _think_ the explanation for that was using pasuspender, and that I no longer get it because I no longer need to use pasuspender - but it's slightly worrying in case that's wrong, and in particular in case it's because I'm leaving some circuit on more than before, and hence drawing more current. (I haven't seen any evidence for drawing extra current.) Overall phone volume is controlled by the addition of the three DAC2 Gain controls, and the new state change implementation never touches those, which means that it's now possible for a volume control widget to change those controls independently, and for that setting to persist. I haven't implemented that yet though. Next up is the A3 software audio routing. I announced a while ago that I had that working with pulseaudio's module-loopback instead of Radek's gta04-gsm-voice-routing program, and I thought that pulseaudio would be the way to go. Since then I've tried to add in echo cancellation, and tried running on an wheezy/armhf system instead of squeeze/armel - which is believed to be advantageous because of better floating point performance, but I've hit various problems. - Just plain loopback, with module-loopback, appears to use a lot (~50%) of CPU, even when running at just 8000Hz, without any resampling, and without asking for particularly low latency. I don't recall how much CPU gta04-gsm-voice-routing takes, but I don't think it was that much. - Pulseaudio needs to be run without RT scheduling, in order to avoid being killed (because of tight-looping) during the initial window between when a call is started and when the GSM capture device becomes readable. But running without RT scheduling reduces the quality of media playback. - Pulseaudio loopback exhibits some odd artefacts. During that initial window (of maybe a second or two) it cyclically replays whatever was last in the device's playback buffer. It audibly does this for what is played through the earpiece/speaker/headset; I wonder if it might do it a bit in the other direction too, i.e. to the other end of the call? It also seems to cause occasional short sound repeats _during_ a call. I think one possible cause of this is divergence between the two sound cards' clocks, hence the buffers being used up at different rates, and at some point Pulseaudio has to choose some strategy for filling in some missing data (to avoid an underrun). I've also frequently noticed that a DTMF tone pressed by me seems to have an effect on the other end as though I had pressed the key twice instead of once, and I wonder if that might be related to repeating or echoing in the audio stream going to the other end. - Despite the WebRTC echo cancellation's apparent good reputation, I haven't been able to get either it or Speex to work effectively. Also CPU usage when trying to do loopback with echo cancellation is 80-90%, even on armhf. (In general, for some reason, it appears that the floating point code in Pulseaudio and its dependencies doesn't run any better on armhf than it does on armel.) The upshot of all that is that I'm now inclined to look more again at the other possible solutions, i.e. gta04-gsm-voice-routing (by Radek) and alsaloop (as used in SHR). The simplicity of gta04-gsm-voice-routing is appealing, but I know from previous experience that it sometimes fails completely. alsaloop in comparison has a drastically different and more

I've pushed my work-in-progress branch to https://github.com/neiljerram/qtmoko/commits/nj, and the relevant commits are those from https://github.com/neiljerram/qtmoko/commit/0062faf815f5b1ede6624acac08bf3b 8ec7040bd to https://github.com/neiljerram/qtmoko/commit/958212671741685ae05de9e2564ea45 272f985d6 inclusive, excluding https://github.com/neiljerram/qtmoko/commit/18404194e37b85a315a64ae23b3ac97 e7dab3256. In summary, these changes: - remove code that I believe has no effect on the GTA04 - simply so as to make the audio-related code overall easier to understand - simplify and clarify the *AudioState classes and related code in neoaudioplugin.cpp - allow for different ALSA state files for A3 and A4 - rename the state files to match the QtMoko domain (Phone/Media) and profile (Headset/Speaker/Earpiece/Bluetooth) names - make the set of A3 state files more consistent with each other. Apart from the last point, all these changes should just be cleanups and have no practical effect. In particular, on A4 there should be no change at all. On A3 the last point may have a practical effect, if the previous switching of 'AVADC Clock Priority' and 'Voice route' values was sometimes causing a problem. I did a load of test calls this morning and had good audio on all of them. That might just be good luck - or it might indicate that that last point really does make a difference for A3. I guess I'll know better after a bit more experience. Anyway, I'd appreciate hearing if you think this line of work looks worthwhile, or any other thoughts you or others have about it.

Apart from that bugfix I don't want to make any assumptions about what time you have to consider this, so please feel free to leave the rest of this hanging for now. But if you do have time and thoughts I'm sure those would be useful, and in any case it's helpful for me to lay out my thoughts. Firstly, I've just pushed some more commits to https://github.com/neiljerram/qtmoko/commits/nj. These are mostly NOT suitable for your Git master, so please don't pull them, but they may help show what I'm doing. First, my previous set of commits _didn't_ make audio in calls any more reliable. My initial tests were just lucky, and in the days after that I had some calls with no audio, the same as before my cleanups. (In fact that was as expected, because the 'cleanups' didn't really fix anything.) Then I looked for a while at the gta04-gsm-voice-routing code. Empirically, - this code often works - giving clear audio - but sometimes fails catastrophically and gives no audio at all - it seems to fail more often when an incoming call causes the phone to wake up from suspend. My guess is that there is an instability in that code which is more likely to strike when other things on the phone are using CPU - such as just after waking from suspend. Perhaps it could something like this: - CPU load causes gta04-gsm-voice-routing to be slow to read the capture devices, so they report overruns - that may cause the code to loop round and try reading those devices again - which now blocks until time has passed to allow more data to be there - when the code eventually gets to the playback devices, too much time has passed, so they report underrun and don't actually play any data - etc. Then I looked at the alsaloop code and my first impression there was how much more complex it is... Putting everything together, my feeling is that this (loopback) is trickier than it looks to get right, and that gta04-gsm-voice-routing sometimes fails because it doesn't cover all the possible variations. So then I looked at pulseaudio, found Neil Brown's old suggestion, upgraded to the testing version, and eventually stumbled across the resampler method change that makes that work (per other email). I've now integrated that in my code: https://github.com/neiljerram/qtmoko/commit/9f78985e8119961cc520e4d050c88bf1e589b879 I then had to make another change to /etc/pulse/daemon.conf: -; realtime-scheduling = yes + realtime-scheduling = no to avoid pulseaudio being killed by the kernel just after starting the loopback. I guess this is the same basic problem as SHR had with alsaloop here: http://lists.goldelico.com/pipermail/gta04-owner/2012-May/002383.html and ideally the fix would be in pulseaudio to initially spin more slowly. But the realtime-scheduling change works too and doesn't impact general media playback too badly (for my taste). But after that, the integrated pulseaudio in-call audio routing seems to work. Of course I'll be more confident about it if I can have a week of it working every time... While doing that I noticed a bug in my previous Rework ALSA state / QAudioState handling commit: it will call gsmVoiceStart() and gsmVoiceStop() even for A4 devices. That's fixed by https://github.com/neiljerram/qtmoko/commit/a362c431531d6b75fcb1894c60e021588ea50d44 so that's one commit that you _should_ cherry-pick. Next what I'd like to do is to make everything louder! There are 3 things that aren't loud enough at the moment: a) the ringtone b) the in-call audio that I hear from the other person c) the in-call audio that the other person hears from me. (b) and (c) depend on good echo cancellation, and I'm hoping pulseaudio's module-echo-cancel will do that for me. I think I can test that, without needing lots of phone calls, simply by playing something (from file) through the earpiece or speaker and simultaneously recording from the microphone. If that works well, we can then just increase all the volumes in the state files. (BTW I think that the Speex echo cancellation in gta04-gsm-voice-routing was less effective because of the playback buffer being 4 times the frame size. This means that when the code sends frame X to ALSA for playback, frame X doesn't actually start playing until 3 cycles later. Therefore we can't immediately use frame X to cancel echo in the microphone sound that we're capturing _now_. I wonder if there was a time when the code had buffer size = frame size, and the buffer size was later increased?) Finally, if all of the above works, we can look at whether it all _still_ works with the squeeze version of pulseaudio. Hopefully eventually the software audio
