For the record, I continue to enjoy this version of mpdpup.

I will likely need to move on to get to newer release, but as of this day, still enjoying it.

Thanks Ildose..

Looks like Ildose is busy or taking a well deserved break.

Does anyone know how to upgrade MPDPUP to use MPD 18?

Hi Idolse. I am usually using MPD on Debian minimal. In the beginning I used a lot of time to toy around with all the usual tweaks, and also some of the more extreme ones. Writing scripts, tweaking the OS to my liking, it took quite a while to get the basics right. Nowadays, I usually spend time li...

boulogne75 My basic ignorance of linux is showing :) Thanks for this insight. It helps. So I tested and confirmed what you said. I open ssh, run ulimit. The limit set lasts until the ssh session is closed, then on reopening, back to default. The sound is changed by issuing the ulimit command. I run ...

Regarding the discussion on ulimit - this is starting to sound like a major research project, I'll see what I can find out though - wouldn't be surprised if the defaults are set at compile time for the kernel. I'm pretty sure I don't want to install PAM or any extra background processes to make lim...

I too have been reading and experimenting where to put ulimit command at startup. I tried at the end of my startup script which is last in the init.d list. No luck. Then I tried in the 20.mpd startup right after the renice. Also no luck. The thing that surprises me most is I leave my system on 7x24....

ok - took the next steps and removed the above items from init.d. Also killed off Albumbler. I do not use it. Sound is very good. I updated my startup script which is in init.d to renice kpmoused to 10 and mpd to -19. This now works on startup. I added the ulimit -l unlimited command to this script....

FWIW, I also removed some processes that were started in the init.d folder that I do not need in my setup. 15.avahi 37.client175 slmodem start_cpu_freq 25.lcd 40.mpdscribble ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ I am going through all the processes one by one and removing everything that is not needed to...

Thank you for the information and test results.


At this point its a fine balancing act.

My pleasure
How do my perceived results compare with your own? I am sure is is system specific to some extent.

... I would like someone to try these two ulimit commands, listen for awhile and post back and difference in sound. ulimit -l unlimited ulimit -s unlimited http://www.linuxhowtos.org/Tips%20and%20Tricks/ulimit.htm I have listened to a few of my favorite test songs, and have toggled back and forth o...

Fin You have made the correct change. You can go back in with nano and see what you now have. You can alternatively use the command less instead of nano to simply list the contents of the file. I always save in nano by using cntrl O then confirm the file then exit. I did not realize you can just exi...

Hi Douwe, Same here. Since I use mpdpup (instead of cmp2) I spent more time listening too music. Mpdpup not only sounds very good but the remote control through smartphone apps also makes it really comfortable. Hi Mark I took similar CMP2 route and concur. Spend a lot more time listening now and lo...

Dynobot
could you show the results of
ps axl
for your system?

Might give me some ideas for what to kill and where priorities should be
thx

Hi Idolse I understand about being too busy in real life....I was extremely busy until recently hence by absence. Now I am looking at about 6 months down time and will spend more time here to discuss MPDPUP. I forgot to post that I also increased the priority of MPD via the file in init.d. Just unc...

Ildose
I may have answered my own question. Rather than create a startup script, I added the commands to rc.local. It appears to work. Parden my inexperience.. Is this a proper approach?
Walter

One other question.. To implement this permanently, is it correct that I put these commands into a script and invoke it on start-up? Where would you put such a script.

So much for measured scientific process. I just put in all the changes listed above in Ildose's post. Sound is very good. At this point the best I have had on this system. I still will play around with buffers etc, but this worked very well for me. Quieter background, continued great sound stage, no...

Jrling Really great to hear you are keen on continuing to push the envelop on mpdpup. The base that Ildose provide is a great jumping off point. I am going to take a while to catch up to you and Dynobot. On the Voyage site, a juy named Jan has built mods to mpd 0.17 that allows real time priority se...

From my experience with CMP minimizing threads and processes that are not needed does help. MPDPUP is already very lean, but clearly there are system specific items that can be killed. Alix users, with just a quick glance it is clear we can kill off bluetooth, video, line printer etc. As a teaser tr...

Hi all I have been away for a while building amps. MPDPUP was working well, so I have not checked in for a while. I just got caught up and it looks like there was a bit of a rally to tune for sound when Dynobot came in. Jrling was on some good paths, but it appears to have dropped. Have you given up...
