still crashing, can this possibly be caused by older kernel?
Linux streamer 2.6.20-16-generic #2 SMP Tue Feb 12 02:11:24 UTC 2008 x86_64 
GNU/Linux
standard kernel from Ubuntu Feisty

/usr/local/bin/jackd -Z -v -d oss -r 44100 -p 4096 -w 16 -i 2

`rotter` works perfectly fine

It would be good to shutdown darkice when this problem occurs? It helps to 
restart stream via scripts.

GoogleCodeExporter commented 9 years ago 
that's what I do right now - restart darkice every time the problem occurs, 
however
this is not a solution since it interrupts the radio stream - not good at all

btw also occuring with the SVN version on Ubuntu 9.10

again - `rotter` works splendidly well

I experienced the same. (I'm not using darkice that often)

I think it's the realtime priority. It doesn't make sense to give the encoder a
higher priority than jackd, because this way, the encoder might block jackd from
running and fetching data from the soundcard which would finally lead to a 
buffer
underrun in darkice.

I'll file a ticket to make the realtime priority configurable. Jackd normally 
runs at
RTPRIO 15 in SCHED_FIFO, so make darkice use 10 or something like this. Right 
now, 98
(which is RTPRIO_MAX - 1) surely is wrong.

If you want to give it a whirl right now, change DarkIce.cpp:1120 from

   param.sched_priority = high_priority - 1;

to

   param.sched_priority = 10;

(and report back if this solves your problem)

HTH

PS: I assume you're running jackd with realtime prios.

Check the comments and proposed patch in issue 21. For jackd users, there's 
usually
no need to set the new rtprio config item, it's only important to have the 
encoder
using a lower priority than the jackd client thread. (that's the thread who's 
getting
the input data from jackd)

I took a look in the patch, and it seems ok.
Do you confirm it's working ok?

I just applied it.
Can I close this issue?

Yes, this issue can be closed.

This solution doesn't work for me...

No way to use darkice 0.20, it shows me "failed to write to ring ruffer" after 
less than an hour.

I tried to compile 1.0 from sources, but nothing to do, same error...

Any Solution?

Got the same problem, I downloaded the patch and darkice1.0 source, patched it, 
compiled, everything is fine, darkice connects to my icecast2 server and jack, 
but after a few seconds it shows "failed to write to ring ruffer". I run debian 
6.0.1 and got jackd1, also i'm quite new, so i'm probably doing something 
wrong. Any ideas?
