Hi I am trying to reduce the speed of my dvd player, i notice a lots of erros on bufferoverflow and my dvd player makes lots of noise while reading a cd audio
[ 2729.597920] Buffer I/O error on dev sr0, logical block 0, async page read
[ 2729.604969] Buffer I/O error on dev sr0, logical block 1, async page read
I believe reducing the speed of the read and writte could stop all those errors i have read that the command eject - x 4 /dev/sr0 would do the job.
Where would you put this command because it needs to be put on each cd insert.
Sounds like it’s starving for power.
I am not convinced about power, cd and dvd’s have defects would those not generate those errors? The speed noise is very annoying though.
A noisy drive and io errors are indicative of a power problem.
By using a slower speed i believe i could reduce power consumption and stop those errors. Could i put this command somewhere that when a cd is inserted this command is triggered?

Fix the real issue, the PSU.

Your power supply probably isn’t up to scratch. You can learn more on our Wiki here: Frequently Asked Questions - Raspberry Pi - OSMC
I am powering the dvd player through a USB hub. The noise is the same if i use my laptop. It’s a loud humming sound.
The default dvd read speed is x24 following eject output.
If the eject command is correct i am turning the dvd speed at 6x less speed i can definitely here the difference.
Do you believe with a new usb hub i will be able to reduce the sound of the dvd spinning in the dvd drive?
If it’s doing the same think while connected to a laptop, then I’d think that would point to the drive as being the issue. You can get external Bluray drives fairly cheap nowdays…
