Help with s905x Analog out on 7.0.2.009

Jaaxx · November 25, 2016 at 5:27 AM

As I understand it, on the latest builds audio should be sent to HDMI, Analog (AV out) and SPDIF simultaneously regardless of the settings in Kodi unless using Bluetooth/Pulseaudio.

I have been banging my head against the wall trying to get analog out working with no success.

I'm running 7.0.2.009 on a X96 s905x 2/16G box. I have also tried a couple of the last devel builds. No dice.

I can see the interfaces:

Code

LibreELEC:~ # aplay -l
**** List of PLAYBACK Hardware Devices ****

The only thing immediately suspicious in dmesg is:

Code

dmesg | grep snd

[    4.017846@1] aml_snd_card: audio use jtag pinmux as i2s output, read val =ffffffff

Am I wrong in assuming that the device tree is correct since aplay -l lists the devices?

Analog audio in S905X is via T9015 codec which seems to have mapped correctly on your device. What kind of audio cable do you use? With my S905X device a standard 3.5mm plug is working well. Can you confirm that analog audio works for you in Android?

Although I now have LE on NAND, analog out was working with android during the brief time I was testing.

I have discovered through alsamixer that Audio i2s and Audio spdif were both muted. When I unmute/mute Audio i2s in alsamixer I can hear a thud through my amplifier, but no further output. Maybe i2s has a hidden mixer control which is currently set to 0?

Hmmmm... only controls for i2s and spdif are MONO switches.

I think this is going to turn into a full bug report soon. Seems no one else is having this issue.

I find this when starting a livetv stream:

And this little bit of oddness at the tail end of "amixer -c 0 contents"

Code

numid=10,iface=PCM,name='Playback Channel Map'
  ; type=INTEGER,access=rw---R--,values=8,min=0,max=36,step=0
amixer: Control hw:0 element read error: Invalid argument

I will setup a fresh SD card with 009 and create a new post with a full bug report and logs as soon as I have a little more time.
