13:44 <BorgCuba> Hi, is the kernel message "dma0: IRQ with no loaded buffer?" dangerous?

13:44 ssvb has joined #linux-sunxi

13:44 <BorgCuba> hi ssvb

13:45 <montjoie> hello, anybody here with the devboard a83T ? it automaticly shutdown when I power up like hdmi/ethernet is necessary to continue booting

13:45 IgorPec has joined #linux-sunxi

13:49 <IgorPec> mainline kernel + cubieboards, lime, ... Is NAND supported?

13:53 <NiteHawk> IgorPec: afaik, nand support is still in development - bbrezillon might know more about the current status

15:23 <wens> jemk: ^

15:24 <pietrushnic> IgorPec: I was able to enable uboot on NAND using Boris code, I did it for Cubietruck and A20-OLinuxino-MICRO, this just uboot UBI/UBIFS not tried yet, but for sure will try in near future

15:24 <pietrushnic> Anyone tried recent sunxi-next with audio in/out ?

15:25 <wens> pietrushnic: only audio out for now, capture isn't implemented yet

15:25 <wens> audio should work for pretty much all boards, as the headphone out is likely directly connected to the audio jack

15:26 <wens> just a matter of enabling the codec in your dts

15:26 <pietrushnic> wens: how to test out I see that special file format is required, aplyay complain that it wants S{16,32}_LE

15:26 <pietrushnic> wens: I have it enabled for Cuibetruck /proc/asound/cards seems to return correct output

15:26 <pietrushnic> wens: alsamixer also show resonable output

15:28 <pietrushnic> BTW anyone tried CodeKipper SPDIF patches ?

15:35 <wens> pietrushnic: i'm using mpg123 to play mp3 files

15:36 <wens> pietrushnic: what file format are you playing? seems like you're playing wav?

15:37 <pietrushnic> wens: yes I tried with wav, I saw this use case in olimex doc

15:38 <pietrushnic> wens: I can try with mp3, have you got any smaples that work ?

15:38 <pietrushnic> wens: or I should try with random one

15:42 <wens> pietrushnic: mine are copyrighted rips from cds i have, probably not a good idea :p

15:43 <pietrushnic> wens: tried this: http://www.stephaniequinn.com/samples.htm mpg123 hangs with no sound

15:43 <pietrushnic> wens: anyway to debug that ?

15:44 <wens> my boards aren't with me

15:44 <wens> have you unmuted the outputs?

15:45 <wens> if it's muted, alsa doesn't take input it seems, it just blocks

15:48 <pietrushnic> I have only serial but, I in alsamixer on playback tab I have one bar active (PA) I raised dB gain to -16, but this not help

15:48 <pietrushnic> BTW F5 crashes alsamixer

15:49 <pietrushnic> F6 also

15:50 iamfrankenstein has joined #linux-sunxi

15:53 <wens> there are Pre-amplifier switches in alsamixer

15:53 <wens> are they un-muted?

15:59 <pietrushnic> I 3 pre-amp DAC, mixer and mute all in Off state

15:59 <pietrushnic> anyway to enable it ?

15:59 [7] has quit [Ping timeout: 250 seconds]

16:00 TheSeven has joined #linux-sunxi

16:02 <wens> arrow keys to move to them, and m to unmute

16:03 <wens> reading the manpage helps :)

16:05 <pietrushnic> sorry, I event didn't consider this can be used and first time used alsamixer over serial

16:06 <pietrushnic> unmuted all but still no sound, but getting short noise when enabling and disabling mpg123

16:14 avph has quit [Ping timeout: 252 seconds]

16:20 <wens> right, you should unmute just the Pre-amp DAC, and Pre-amp Mute, not the mixer

16:20 <wens> if you unmute all of them, seems they cancel out

16:24 <pietrushnic> alsamixer: http://code.bulix.org/afqi8q-89370

16:24 <pietrushnic> mpg123 -vvv: http://code.bulix.org/hwbzr1-89371

16:24 <pietrushnic> still not sound in headphones

16:29 <pietrushnic> wens: do you use -a param ? if yes that device which device file you provide ?

16:29 <wens> nope

16:30 <wens> looks good to me
