Oh dear, waking up an old thread here...
Just wanted to tell you that I'm using Samsung SH-224BB drive - the speed is 48x - and setting the drive speed to 24x (setcd -x 24 /dev/sr0) works. However, Samsung states at the MAGIC SPEED page that it doesn't affect DVDs, only CDs. This could be somewhat true, because setting speed 10x has no effect on speed/noise, but setting speed 24x does it make it very silent. So, I know my drive supports speed 24x for DVDs, too, via setcd (at least). How do I make it permanent? Setting it to rc.local doesn't seem to do the trick, as my (still ongoing) experiments suggest. Is it possible to make the command run every time right after the disc is inserted via the open/close tray menu item? Or perhaps during XBMC startup? While I know my way around Linux, XBMC insights are all new to me. Any pointers? Home.xml? Thanks all, in advance! -- Direc |

Oh dear, I just couldn't go to bed until I got this done...
So, after some serious trial and error, I ended up with /lib/udev/rules.d/99-cdspeed.rules file like this: Code: ACTION=="change", SUBSYSTEM=="block", KERNEL=="sr0", ENV{ID_CDROM_MEDIA_STATE}=="complete", RUN+="/sbin/hdparm -E24 /dev/sr0"The rule activates only after the disk mount is complete (or something). The only hiccup is that the speed actually changes only after the first read from the disk (when the playback starts), but I can live with that . So there you go, a way to adjust the speed once and for all. I think the 24x option doesn't work for everybody, but try different values so that you find one that works.Oh yeah, I'm running fresh XBMCBuntu 12.0 here, in case that matters. Hope this helps someone else, too. -- Direc |
