Much appreciated yet again vpeter - agreed that it is probably something else that is causing the stuttering. Will test with music on a USB drive as it may be the NAS I'm streaming from that is causing the issue.

Marked as solved.

Hi All,

After noting that some music I was playing was skipping I've noticed that my CuBox i4-pro is only running at 100Mbps on the network. I believe the fault lies on the CuBox itself; here's the troubleshooting I've done to establish that:

• Other devices plugged in to different ports on my router get gigabit speeds.
• The CuBox, when plugged in to these other ports, still only gets 100Mbps speeds.
• The CuBox, with a different 1m Cat5e cable, still only gets 100Mbps speeds.
• The Cubox, with this different cable, plugged into another gigabit switch, still only gets 100Mbps speeds.
• My laptop, with this different cable, plugged into both the router and the gigabit switch, gets full gigabit speeds.

To confirm I should be getting gigabit, I checked the manufacturers page (SolidRun | Simple Robust Embedded Computing Solutions

Ethernet:    10/100/1000 Mbps (*)

(*) Note that due to internal i.MX6 buses the 1000Mbps interface speed is limited to 470Mbps.

I've started looking at the CuBox and it seems to report that 100Mbps is the maximum:

CuBox:~ # ethtool eth0
Settings for eth0:
        Supported ports: [ TP MII ]
        Supported link modes:   10baseT/Half 10baseT/Full
                                100baseT/Half 100baseT/Full
        Supported pause frame use: No
        Supports auto-negotiation: Yes
        Advertised link modes:  10baseT/Half 10baseT/Full
                                100baseT/Half 100baseT/Full
        Advertised pause frame use: No
        Advertised auto-negotiation: Yes
        Link partner advertised link modes:  10baseT/Half 10baseT/Full
                                             100baseT/Half 100baseT/Full
        Link partner advertised pause frame use: Symmetric Receive-only
        Link partner advertised auto-negotiation: Yes
        Speed: 100Mb/s
        Duplex: Full
        Port: MII
        PHYAD: 4
        Transceiver: external
        Auto-negotiation: on
        Supports Wake-on: g
        Wake-on: g
        Link detected: yes

I tried setting the speed manually with:

ethtool -s eth0 speed 1000 duplex full autoneg off

but it just drops the connection and brings it back up at 100Mbps.

Any ideas?!

It is small black cube (i4p I think).

Sounds about right. Oh well - bit of a mystery why yours works

Quote from Iridium

Might not be relevant but what version of LE 8 are you using? vpeters 3.14 kernel?
Also, have you got the small toslink connector - most normal ones are too large to fit in the cubox with modification. It gives the impression that it is connected, but is not.

No, just the official one. And yes I've got the toslink connector as I ran into that issue as well.

Next step the 3.14 build then you think?

OK - Popped the 3.14 Kernel version (form here: Index of /imx6-solidrun-kernel-3.14/) into the 'update' share and rebooted and it's working fine now.

Interesting that yours works OK vpeter - is it a CuBox you have or another device? Either way - appreciate the 3.14 build.

I checked spdif only when I add it. I assume this was for LE7. But didn't checked on LE8. Will do over weekend.

I found 10 minutes free time and check this: it works fine for me. Hope I connected everything correctly If I unplug spdif cable then sound is lost. When plug back sound is back too. Test successful.

Cheers vpeter - appreciate what you do to bring LibreElec to i.MX 6 devices.

Hi All,

Had a look through the forums, Google, LE8 release notes and the Kodi Audio Quickstart guide but can't seems to get any sound out via S/PDIF. For the record, it works OK via HDMI.

Dmesg seems to indicate that it is detected OK, and I've tried both the 'default' option and selecting S/PDIF manually. Have also enabled passthrough to see if it makes a difference but nothing. I had the same issue when I tried one of the beta builds and just downgraded back to 7.0.2 and it worked again, so I'm ruling out broken hardware.

CuBox:~ # dmesg | grep spdif
[    2.218517] imx-spdif sound-spdif: snd-soc-dummy-dai <-> 2004000.spdif mapping ok


[    2.246172] ALSA device list:
[    2.246187]   #0: imx-spdif
[    2.246193]   #1: imx-hdmi-soc

Any ideas, and any other log files I can sift through to find an answer?

Much appreciated.
