<bmbeach> wizzup: do you get sound on snow when you -> don't <- enable pulseaudio

<Wizzup> hi
<Wizzup> bmbeach: watching the moon atm
<bmbeach> no hurry
<Wizzup> I get *some* sound
<Wizzup> but it's not proper
<Wizzup> you need to unlock the right switches
<bmbeach> thats what I'm wondering
<bmbeach> I should be getting sound
<bmbeach> but
<bmbeach> I get nothing
<bmbeach> yet it goes through the motions as
<bmbeach> if it was playing the songs
<bmbeach> what switches
<bmbeach> if you mean the mixer
<bmbeach> I enable everything except for
<bmbeach> (I need to look it up hang on)
<bmbeach> except for biquad
<Wizzup> left speaker left dac? left speaker right dac. etc.
<Wizzup> same for right
<bmbeach> yes they are all enabled. are you getting sound on
<bmbeach> the speakers or the headphones or both?
<Wizzup> both
<bmbeach> How about when you say *some* sound. what do you mean
<Wizzup> it kruns too fast and ticks
<bmbeach> do you get buffer overrun and underrun messages at all
<Wizzup> I don't know atm.
<Wizzup> probably.
<bmbeach> these come up on the kernel logs, not in userland
<bmbeach> have you tried the diagnostics in u-boot?
<Wizzup> I also got 'PLL unlocked' messages
<Wizzup> but I need to look into sound
<Wizzup> just didn't have time yet
<bmbeach> I've been working on it for months
<bmbeach> on something but I just don't get sound
<bmbeach> the speed thing I can figure out eventually
<bmbeach> what I can't figure out is that
<bmbeach> I'm running basically the same kernel as you (4.2)
<bmbeach> and a very recent u-boot
<bmbeach> yet you get sound and I don't
<bmbeach> The pulse audio
<bmbeach> thing is that I don't run it and
<bmbeach> thought may it was enableing something but
<bmbeach> apparently not.

<javier__> if someone is interested, I wrote a small blog post about using a mainline kernel and linux distro on exynos chromebooks http://blogs.s-osg.org/install-linux-mainline-kernel-distro-exynos-chromebooks/
<Wizzup> javier__: cool, mostly seems to cover the 'booting' part
<Wizzup> although I guess some fedora stuff is specially prepped to 'just work'
<javier__> Wizzup: well, everything worked for me on peach pi modulo audio that still has the overrun, unstable issue
<Wizzup> nice :)
<javier__> I'll try to get some time this week to look at that
<Wizzup> what ddx does fedora use?
<Wizzup> javier__: awesome!!
<Wizzup> If you need me to debug anything - just poke me
<javier__> Wizzup: Ok, thanks
<Wizzup> I've been playing with sunxi hw (for work) and hobbying with the n900 (for fun) lately - exynos got to the point that it's very usable day-to-day (been using exynos hw exclusively for two years now)
<Wizzup> not that I'm a particuar exynos fan, but the chromebooks are nice :)
<javier__> Wizzup: not sure, about the DDX. I should take a look
<Wizzup> yeah, I mostly don't have any gpu accel
<Wizzup> It is only/mostly painful when I'm "moving" windows
<Wizzup> but since I use a tiling wm, it's mostly a non issue
<Wizzup> although video scaling just ...yeah
<javier__> Wizzup: yeah, I think is interesting to have mali support with mainline though so I'll try to find some time to poke at that
<Wizzup> would be cool too
<javier__> although probably that would end in my TODO list forever..
<Wizzup> hah
<Wizzup> yeah, personally I don't care for closed source gpu drivers
<Wizzup> I've been considering taking an ifc6410 and building a laptop around it
<javier__> Wizzup: what's the state of the N900 btw? I believe it will be mostly unusable due the same issue: PowerVR SGX not working with mainline
<Wizzup> Well, there's a patch that seemingly makes it work
<Wizzup> (on top of mainline)
<Wizzup> The status is actually quite decent.
<javier__> I've an N9 here but still running the stock MeeGo "Harmattan" from Nokia
<Wizzup> I've got X to work, audio too, wifi just works, usb works (host mode not yet), charging works, emmc, sd card, works
<Wizzup> leds work :)
<Wizzup> the next item to tackle is the modem -- is suppose to work, but didn't get it to work yet
<Wizzup> at least the data part should work - voice support in modem is also there, but requires userspace pulseaudio binaries
<javier__> hehe, I in fact maintain a family of OMAP3 boards (IGEP) so I think it should not be that hard
<Wizzup> which need to be reverse engineered at some point
<javier__> probably it is well supported
<Wizzup> what particularly?
<Wizzup> (I'm kind a n900-nut actually, I have about 8 of them lying around, just to have them in case my current one breaks)
<Wizzup> bought them cheap, used state
<javier__> Wizzup: what OMAP3 boards I maintain you meant?
<Wizzup> javier__: I meant, what should not be that hard?
<Wizzup> but I'm hoping to help reverse engineering the final parts for voice support for the modem, and then I can have a truly open (driver) 'phone'
<javier__> Wizzup: ah, sorry. Getting N9 to work
<Wizzup> ah, yeah
<Wizzup> Maemo people would love that probably
<javier__> since OMAP3 is well supported and I see there is an N9 DTS already
<Wizzup> yep
<Wizzup> oh yeah, touchscreen also works
<Wizzup> basically you can just run xfce on there on something -- not particularly mobile friendly though
<Wizzup> s/on something/or something/
<javier__> Wizzup: but yeah, for a complete meamo / meego user-space, there is a lot of closed source binaries from Nokia
<Wizzup> well, the maemo people are working hard to have an open core
<Wizzup> the voice part is the last big hurdle, as far as I hear
<Wizzup> d
<Wizzup> And people got maemo to work with a more recent kernel (I don't know well it works, but boots, etc)
<javier__> I also have a Nook Color here that it's also OMAP3 based so that should work with mainline as well
<Wizzup> So with a bit of luck, at some point maemo can be updated to a newer kernel, glibc, etc
<Wizzup> ah
<Wizzup> nice
<javier__> before getting involved in Exynos I was very involved on linux-omap so I've a lot of omap3 hw here :P
<Wizzup> nice
<Wizzup> I also have the n800 and n810 lying around here
<Wizzup> No immediate plans to hack on them though :)
<javier__> yeah, I don't have inmediate plans to hack on the Nook and N9 as well but would love to have some time so I can undust those
<Wizzup> I like the hardware keyboard with the n900
<Wizzup> otherwise, yeah, n9 is awesome too
<Wizzup> I actually ordered the neo900
<Wizzup> so I'm really looking forward to that working out too
<javier__> cool, I see a lot of work being done on the GTA04 platform on linux-omap
<javier__> anyway, I guess we should move this conversation to #linux-omap or something since is out of topic here :)
* Wizzup joins
<Wizzup> but yeah -- if you want me to test some audio stuff, let me know
<Wizzup> I'm actually still on v4.1
<Wizzup> mostly because grsec has not released v4.2 yet - but I can easily go and test v4.3-rcX + patches
<javier__> Wizzup: will do since I don't have access to a Snow anymore (some of my co-workers do though)
<Wizzup> I have a snow here, that's currently not used as main machine, so can experiment
<javier__> Wizzup: cool
<javier__> first step is to add support for Snow Rev5 that has a max98090 instead of a max98095 codec
<javier__> I've a patch for that already but need someone with a Rev5 to test https://github.com/martinezjavier/linux/commit/397ead8befa9da50a63584a8a41956401312d76d
<Wizzup> ah... nice...
<javier__> Wizzup: I believe yours is Rev4 though
<Wizzup> wondering - what's the easiest way to find out the snow rev?
<javier__> Wizzup: boot the stock Chromeos and look at /proc/device-tree/compatible
<Wizzup> right
<javier__> but I'm almost sure yours is Rev4 since the max98095 codec driver probed for you
<Wizzup> yeah
<Wizzup> or it's not -- and it somehow explains the weird audio issues, but I doubt it :)
<javier__> I remember someone mentioned that failed for him and had a Rev5 but I can't remember who...
<javier__> Wizzup: no, the codecs sits on a different I2C address so on a Rev5 it won't be probed
<Wizzup> :)
<Wizzup> ack
<javier__> Wizzup: the weird audio issues is something else... I still don't know what though
<javier__> I *believe* is clock related but I may be wrong
<Wizzup> yes
<Wizzup> I noticed that on boot, when I first use it
<Wizzup> it runs just a bit too fast
<Wizzup> if I keep writing, it runs ~1/0.91 too fast
<javier__> hmm, interesting
<Wizzup> (keep writing = fire up pulse, aplay -f /dev/zero ; play other stuff)
<Wizzup> that is 44.1/48
<Wizzup> but at some point ... it just plays even faster
<Wizzup> and gets more choppy
<javier__> so it could be something about the clock hierarchy, a wrong divider or something like that
<Wizzup> mm
<javier__> anyway, I should leave since is quite late here, have a good night!
<Wizzup> same here - 1am
<Wizzup> good night!
