10:39 Sashimi hi all
12:44 Mynameisbiff Hi guys
12:45 Mynameisbiff Was hoping someone could offer some assistance for a troubleshoot I'm currently doing with my parents
12:47 Mynameisbiff I gave them a cubox with Kodi (purchased from official site), and a hard drive loaded with media. I tested it with them on a TV and everything worked well: I simply connected the HDMI cable and all was hunky dorey
12:47 Mynameisbiff THey then took it home with them (other side of Australia) and have plugged in to their home tv. They get picture but no sound
12:48 Mynameisbiff Im troubleshooting over the phone with my 70 year old parents, so its a bit of a headache, but so far I've done the following:
12:48 Mynameisbiff Made sure the TV produces sound on another input
12:49 Mynameisbiff Used the keyboard volume keys to make sure the sound isnt muted, and volume is turned up
12:49 Mynameisbiff tried multiple different media files
12:49 Mynameisbiff Is it possible that particular TVs might not be compatible with the HDMI audio inout?
12:49 Mynameisbiff input*?
12:52 Mynameisbiff CAn anyone offer any suggestions? THanks in advance
12:53 dexter93 Mynameisbiff, I'd check connections, and that the tv supports audio over hdmi.. early ones didn't like it
13:09 R0nd could kodi default to spdif? might be worth checking
13:10 Mynameisbiff r0nd, thanks for the input. Excuse my ignorance, but what do you mean by that>
13:11 dexter93 the cubox supports audio output from spdif as well as hdmi
13:13 R0nd and it's managed from kodi settings
13:33 mk01 Mynameisbiff: resolution must be CEA
13:34 Mynameisbiff sorry guys not sure what that is? can you elaborate
13:34 mk01 hdmi audio is driven by pixelclock of video signal, but that must match some predefined intervals.
13:37 mk01 Mynameisbiff: ok, basically the resolution must be one of - https://github.com/linux4kix/linux-linaro-stable-mx6/blob/linux-linaro-lsk-v3.14-mx6/drivers/video/mxc/mxc_edid.c#L41
13:38 mk01 screen must support those through EDID info, ,,, only then HDMI mode is choosen on boot with audio enabled
13:38 mk01 otherwise DVI mode is choosen with audio = NO
13:44 Sashimi hi all !
13:45 Sashimi thought i should ask : i've had the cubox i4pro for some time, it's collecting dust, so i'm trying to sell it. anyone in france on this channel and interested ?
13:46 mk01 Mynameisbiff: but anytime use USB DAC or SPDIF
13:46 mk01 sound there is not affected
13:46 mk01 always cheaper than buying new TV
13:47 Sashimi mk01 USB DAC support is flimsy
13:48 mk01 Sashimi: with pulseaudio the output is in contrary quite good
13:49 Sashimi mk01 kernel issues : clicks are heard
13:50 Sashimi haven't been resolved in nearly a whole year
13:54 mk01 Sashimi: if you say you had clicks I believe you, but I get pretty decent sound out of it (to my surprise because XBMC used to be bad with pulseaudio in general). but I get distortion only if resampling (or with audio) above 96khz with 24bits
13:55 Sashimi mk01 it must depend on the USB DAC
13:55 mk01 honestly, this I don't know
13:56 mk01 I just have Denon 32ch mixer with USB and NativeIntrument box and both are well
14:19 Mynameisbiff OK solution has been arrived at:
14:19 Mynameisbiff after 3 restarts, we now have sound.
14:19 Mynameisbiff After all that
14:20 Mynameisbiff And now their logitech mouse isnt responding but the keyboard is (its an all in one) I think theres a fair bit of old people fuddery at play
14:21 Mynameisbiff thanks for the input all
17:44 smairi is it all sources of cubox are opensource ?
17:46 smairi i mean is there any limit when i compile the kernel sources ?
17:48 smairi like a linux kernel version or other limits
17:51 Catwich there are binary-only pieces of software
17:51 Catwich wireless firmware, media codecs, graphics libraries
17:52 Catwich however bootloader and kernel are completely open-source
17:52 Catwich support for the cubox-i is in mainline-linux, although with a few problems
17:52 Catwich and there is a 3.14 kernel by solidrun which they make sure works best and fully supports the hardware, including those binary blobs mentioned before
17:54 smairi can i run linux kernel from kernel.org ?
17:54 Catwich yes
17:55 Catwich thats mainline
17:57 smairi i can run linux kernel 4.0 ?
17:59 Catwich not sure if anybody tested if tehre is a blocking bug right now
17:59 Catwich but otherwise, yes
