I have a self-powered Blue-Ray DVD player (LG BE16NU) connected to Vero4K. In the beginning no problem with autoplay of audio CD’s en DVD’s. In recent months autoplay is not working anymore and I see buffer I/O errors in the log when inserting an audio CD https://paste.osmc.tv/zotilitabu
If I mount a DVD I can see it in the video files and start it from there.
Strange thing is that this DVD player is working without any problem on a Windows 10 pc with the same audio CD’s or DVD’s.
Anyone can help me ?
[ 68.794355] Buffer I/O error on device sr0, logical block 0
A few possibilities:
- Disc is damaged (unlikely)
- There is a power issue – and the drive isn’t getting enough power
- There’s some sort of copy protection active.
Do you have a CD that won’t be protected (such as a software disc) that you could try?
Sam
Hi Sam,
thanks for your feedback.
I have tried with a software disc and this is working allright without buffer I/O errors.

So, maybe a copy protection issue ?
The drive has its own power supply, so I don’t think it isn’t getting enough power
I think the issue is that Kodi needs to open it as CDDA.
We do build Kodi against libcdio; but I note we pass --disable-optical-drive. I think this is because we expect UDisks to handle things; but it won’t be able to handle an audio CD.
I can produce a test build if you’re willing to give it a go.
Sam
hello Sam,
Sure, I am willing to give it a go with a test build.
Thanks in advance
As I read the specs for the quoted model, it gets power through its USB connection!
Derek
hi Derek,
I have to disagree with you : the drive has a power connection with AC adapter.
See owner manual on LG BE16NU50.AVAR10B: Support, Manuals, Warranty & More | LG USA Support
Thanks for the info - the specs detail suggested otherwise, with no mention of separate PSU.
Derek
Checked this – I don’t think a new build is needed.
Can you change ‘handlemounting’ to 1 in advancedsettings.xml?
<?xml version="1.0" encoding="UTF-8"?>
<advancedsettings>
<handlemounting>1</handlemounting>
</advancedsettings>
Sam,
perfect ! that solved the problem 
audio CD’s are playing fine now.
thanks for your time.
Geert
Thanks for letting me know.
I will need to think about a proper solution
Sam
