[PD] harddisc activity blocks sound playback - solved!

[Norbert Math]

hello,
first i want to thank you for the suggestions!

i got the problem near to solved by increasing the
buffersize as guenter suggested. 
 
pd 0.34.2,  s_linux.c, near line 666:
...

   if (linux_fragsize)
           /*   post("warning: overiding blocksize to 64!");
            linux_fragsize = 64; */
              post("hack: warning: overiding blocksize to 1024!");
            linux_fragsize = 1024;
        }   
...

i still get loops sometimes - they sound lovlier now :-) but i can 
rearrange the pd patch o avoid them.
on the long run i consider to apply the low-latency kernel patches.
(demudi will come with them, i guess?)

thank you all again
