01:40:28__builtinhmm, where does it reference thread_remove?

14:21:18 Join krabador [0] (~krabador@unaffiliated/krabador)
14:29:25pamauryqvr: not that I am aware. at least the NW-A30 uses the same form (but different encryption so we are stuck). I don't know what the srs-zr5 is
14:30:51pamauryit might be that Sony used the same extension for other producst but never used the same format
14:32:45qvryeah, ok. it's a wifi speaker (chromecast audio, spotify connect etc).
14:33:17pamauryI guess it's all encrypted?
14:33:30qvryeah, seems so
14:35:01pamauryqvr: what happens when you connect the device via usb, does it connect as mass storage?
14:36:46qvri might try that next, but i think it'll only work in usb host mode
14:42:54*pamaury has a look at the upg image out of curiosity
14:47:59pamauryyeah, could be a totally different format or the same with a slight change but the possibilities are huge

16:51:01gevaertsYes
16:51:13pamauryis it 1=provide download link?

16:51:32gevaertsSo yes
16:51:36gevaerts(indirectly)
16:52:52pamauryand what is the number after rockbox.zip?
16:53:44gevaertsRelative build cost
16:54:02gevaertsAlso defined as "centiseconds on my laptop" :)
16:54:28***Saving seen data "./dancer.seen"
16:54:32pamauryhmm, the number look pretty arbitrary
16:55:19pamaurylike zenxfi2 has 91430 but zenxfi3 has 202070 which sounds wrong
16:55:24 Nick SovietShaman is now known as CommunistWitchDr (quasselcor@97-87-177-85.dhcp.stls.mo.charter.com)
16:56:00gevaertssims have the same sort of difference for those
16:56:17gevaertsMaybe at the time one of them didn't have most plugins?
16:56:33pamauryhmm, unless there is a big difference in terms of plugins, I don't remember tweaing those numbers
16:57:01gevaertsThey both come from the same measurement run
16:57:11pamauryso you did measure them?
16:57:21gevaertsYes
16:57:57gevaertsWell, the ones that were there at the time. ibasso was added later
16:57:58pamauryok, I'll put a more or less random number of the E580 and I'll let you bench it ;)
16:58:20gevaertsLet me guess, I'll need a new toolchain? :)
16:58:54pamauryyes :)
16:59:44gevaertsGreat!

17:00
17:00:15pamauryit might require apt-get install libmpc-dev libmpfr-dev libgmp-dev
17:00:43*pamaury added one build with the new toolchain and will try to trigger the build server
17:01:02 Join idonob [0] (~Owner@S010600259c3e7d7b.vs.shawcable.net)
17:01:35gevaertsOK. I think I'll install toolchains on my new PC at home which is a tiny bit faster (5 years newer!) than my laptop and do a calibration run on that
17:01:57gevaertsMy laptop fan tends to be noisy for hours during those :)
17:03:35gevaertsWill this replace the old ypr0 toolchain that nobody can build?
17:04:08pamaurygevaerts: I would like it to replace it yes
17:04:23pamauryWe need to confirm it works on both ypr0 and ypr1 before switching though
17:08:02pamaurygevaerts: what is the rule for CREDITS? If I push a commit on gerrit from someone, I should add him to CREDITS right?

20:55:00johnb3Same here and thanks for including the A20.
20:55:46pamauryyou're welcome. I still need to update the wiki and upload some bootloader builds. There are still many things to fix and probably the bootloader can be improved
20:56:02pamauryalso there is a problem on E450/E460 where audio stutters when backlight is off :(
20:56:27lebelliumDid we solve the sound issue on E580?
20:56:33lebelliumI don't even remember
20:57:03johnb3I don't think completely.
20:57:25johnb3I wanted to record a signal and see the steps next weekend.

20:58:24lebelliumI'll try to spend some time on Rockbox this weekend. I still have to test the Yp-r0 patch... :/

21:00:22pamauryjohnb3: there is a bug with audio volume but I know why and it can't be fixed until I do some work on the DSP
21:02:23johnb3ok. I tried to understand your algorithm for creating the volume, but did not understand it immediately :-/ Then I will postpone the measuring.
21:03:54pamauryI realized today there is a bug in my algorithm anyway, it's wrong by a factor of 2. The steps are 2dB instead of 1dB
21:06:53lebelliumis it possible to get the usual volume display (negative) instead of starting at +0 which f**ks up themes with a graphical volume bar?
21:08:03pamauryI'm pretty sure the current code doesn't start at 0dB
21:08:12pamauryit starts at something like -50dB
21:09:02lebelliumah, I may not be up to date. I'll check this weekend
21:09:07pamauryactually it ranges from -100dB to 4dB
21:09:37lebelliumnice
21:10:05lebelliumyou must have done some progress since the last time I used a NWZ :P
21:12:48lebelliumare you still doing something with the A860?
21:24:57johnb3BTW, I have updated g#1591 to activate the pitch screen on Longpress Up. Tested with the pushed NWZ commit on E450, E580 and A20 ;-)

22:04:19pamaurylebellium: so the A860 is a bit weird because of touch screen and buttons that are different from the other nwz players
22:04:36lebelliumweird I don't know
22:04:40lebelliumat least different!
22:05:05pamauryI guess the big question is do we want/need a completely different keymap
22:08:53lebelliumWe'll probably need to accept that some functions can only be used through the touchscreen, that means it depends on the theme you're using (or using the grid mode)
22:12:52pamauryyes, but the current nwz keymap kind of requires directional arrows so I suspect we want a separate keymap

22:22:41pamaurylebellium: I suggest power off on long home, is that consistent with OF
22:22:42pamaury?
22:31:45lebelliumI assume there is not much choice. Either long press on Home or on Play/pause right?
22:32:17pamaurypretty much...
22:32:48lebelliumHome is maybe more natural
22:32:53lebelliumas bigger and more visible

22:47:59[Saint]Just sayin'.
22:50:47wodzAtj has single analog output stage volume control (applied both to left and right channel uniformly). Does it mean I should set it to max and define HAVE_SW_VOLUME_CONTROL to actual attenuation? Or should I use 'hybrid' mode and set base in analog stage and possible difference in SW?
22:51:06pamauryon the A860 this would be a strange choice I feel since it's a little button on the side but I don't feel stronly about it
22:51:48wodzpamaury: Do you have any opinion on how should I implement volume control on ATJ?
22:52:41pamaurywodz: on NWZ I use a hybrid approach, but currently I don't use HAVE_SW_VOLUME_CONTROL because of some weirdness in the nwz driver. But I'd like to use HAVE_SW_VOLUME_CONTROL eventually, I am just not sure if this hybrid mode is supported by HAVE_SW_VOLUME_CONTROL
22:52:52pamauryin any case I'm definitely interested in having such a mode
22:54:37***Saving seen data "./dancer.seen"
22:55:18wodzwith HAVE_SW_VOLUME_CONTROL you simply call pcm_set_master_volume(sw_volume_l, sw_volume_r) in audiohw_set_volume(). So AFAIK you can set base volume in HW and in SW adjust only difference.

22:55:57pamaurywodz: oh cool, then I'd say go for hybrid
22:56:07 Quit p3tur (Quit: Leaving)
22:59:15saratoga_how well does hybrid actually work given the latency in the PCB buffering? Do you get weird effects where changing the volume goes in stages?
23:00
23:00:40wodzsaratoga_: Don't know yet.
23:00:48pamaurywell at the moment I use a horible hack in the pcm alsa driver so changing volume produces artifact anyway. I didn't pay attention to the latency to the honest
23:01:38wodzheh we even have AUDIOHW_HAVE_MONO_VOLUME (seems to be used only in sdl driver and no target defines it)
23:01:39pamaurybut I would expect the pcm volume to be very late in the pipeline so the latency should be very small no? But I can see how this can be a problem though if hw and sw volume are not synchronized
23:03:58pamaurybut the idea of hybrid volume anyway is that you should usually adjust either using hw or sw in ranges. For example between -50dB and 0dB you would use harware and between -100dB to -50dB you set hardware to -50dB and use software. Thus only one of hw/sw changes when you step up/down
23:03:59*pamaury needs to find a way around the database refresh on NWZ

23:07:10wodzah, no mas35xx, uda1341, dx50, dx90 and maemo5 seems to use mono volume control

23:12:20wodzSo easy route is to define MONO_VOL_CAP and forget about balance.
