10:00 xobs flips, not sure if anyone responded on this, but sounds like you need to disable overscan on your TV.
10:15 vpeter xobs: If tv has this function.
10:16 xobs It's usually called something like "true scan", "computer", or something similar.
10:17 vpeter Mine doesn't hve anything. But it is little old. Maybe that's why :-)
10:18 jnettlet xobs, pengutronix pushed a new patchset for etnaviv-drm, with patches for xorg-video-armadafb. rmk will probably review later today he said.
10:18 jnettlet looks like the patch is stuck in the kernel mailing list moderation though
10:19 xobs jnettlet, I noticed that. Exciting stuff. Looks like there's mention of an Xorg driver, too?
10:20 jnettlet just patches to rmk's driver, I haven't had a chance to see what they changed. May just be compatibility for the kernel api changes that were made
10:21 jnettlet xobs, yep just checked. kernel compatibility changes
10:21 jnettle 10:21 * jnettlet must venture out to procure food like substances
10:24 xobs Enjoy.
10:24 xobs I wonder how their 3D driver is progressing.
12:12 flips xobs: it's a plain monitor (not a tv, 5-6 years old), there is a setting for manual either computer mode or HD mode. One of them turns all colors into weird green (still with this issue) and the other has just this issue ... :)
12:14 jnettlet flips, you would need HD mode with our driver
12:16 flips Where can I buy that? ;)
12:17 jnettlet flips I thought you said "there is a setting for manual either computer mode or HD mode"
12:17 jnettlet did I misunderstand. I know that was common in older HD monitors.
12:20 flips I misunderstood, thought you said I needed to load a special mode with the driver
12:30 jnettlet nope, so those two modes basically mean, use Vesa modes, or use CEA modes. While we have added vesa mode support to the driver CEA is probably a better choice.
12:31 jnettlet if neither are working then I will need to look into it, but I am traveling until the end of next week and won't be able to really look into it until after then.
12:56 flips well, it runs in PC Mode. If I select HD Mode, the screen turns green, and I still have the "overscan" issue. If I turn off and back on the monitor, it autoswitches back to PC Mode ...
12:57 jnettlet flips, what if you switch to HD mode and then reboot the board?
13:13 Artox good day everyone
13:14 Artox I have seen a asoundrc file somewhere that properly configures the sound devices on cbi and hb, so that e.g. alsamixer has volume controls for spdif out put too. Does anybody know where I can find one of these?
13:22 flips jnettlet: The monitor switches back as soon as the modes change for for firmware/u-boot etc ... (BTW only tested debian fb and OpenELEC/Kodi, not X in plain Debian this time around)
13:40 Artox I could be using this one: https://github.com/Freescale/meta-fsl-arm/blob/master/recipes-multimedia/alsa/alsa-lib/0001-add-conf-for-multichannel-support-in-imx.patch
13:40 Artox jnettlet: is that advisable?
13:41 Artox and, is CS42888 the SPIDF output?
13:43 Artox or are these the right ones?
13:43 Artox https://github.com/CrawX/PKGBUILDs/commit/c108b6e0fb4323d7fa6d4f5d2ac254a462b3980a
13:43 Artox they look much more like the ones I remember
13:46 mk01 Artox: the latter link is what is generally used (and is tested) with Kodi
13:47 Artox thanks, mk01
14:00 Artox mk01: do you know anything about a mixer control showing up in alsamixer?
14:00 Artox for spdif?
14:02 mk01 spdif/hdmisoc do not have mixer control. there is nothing to control in the first place.
14:03 Artox okay
14:03 Artox so how does volume control work then (I have seen pulseaudio do it)
14:04 mk01 pulseaudio is preprocessing every audio channel
14:04 mk01 by default
14:05 mk01 pulse is sound server - alsa is more like low level driver(s) set
14:08 Artox Ah
14:08 Artox so I could e.g. use dmix to add controls I guess
14:10 mk01 yes, you can do things like that by creating "alsa analog pcm" device
14:11 mk01 what will do some preprocessing on specified source as per conf. but never tried and my knowledge ends here.
14:11 mk01 what you want to achieve ?
14:11 Artox when I do video playback tests
14:11 Artox and attach my spdif->analog converter->speaker
14:11 Artox I dont want it to scream awake the whole house
14:12 Artox (speaker doesnt have a control)
14:12 Artox also, it'd be nice to provide a mixer in xfce, or mate
14:12 Artox *without* the need for pulseaudio
14:12 mk01 ah understand. and the analog converter has no control (or for sure not remotely available, right?)
14:13 Artox no control
14:13 Artox if there are special signals available, idk
14:13 mk01 yes, I suppose for your case this could work
14:14 mk01 try reusing imx-spdif.conf as template
14:14 mk01 and add dmix controls
14:15 mk01 (check other alsa configs or some google). I have the feeling out of interest I was trying that, but don't remember more.
14:17 mk01 Artox: check here http://alsa.opensrc.org/Dmix
14:24 jnettlet well spdif only has a signal, so you need to create a virtual device with a virtual volume control that reduces the gain before it hits the SPDIF
14:43 flips openelec has volume control on the spdif out, I haven't looked into how they did it ...
15:02 Artox thanks, mk01: that looks liek a very thorough document
15:02 Artox I'll bookmark it for now
15:02 Artox looks like dmix can do exactly what I want, and the howto even says how
15:02 Artox virtual slave device
