ProAudio repository for Arch users

That's what I thought. I've applied your patch to 0.9.4 only.
yes, it's really strange. never had that before. the md5 checksum may fail on apps PKGBUILD but apps still builds.

Hey Shinlun,

sorry to keep going on about hydrogen-0.9.4 but I've tried it on SuSe and it works well.
the important thing is mute groups.
I need the hi-hats to sound more really.

I now have 0.9.3 work again but the svn-hydrogen I would like to run on Arch as Suse gives tons of xruns. I using their JackLab version.

patch -Np0 -i hydrogen-snapshot-flac.diff
patching file flac_file.cpp
patch unexpectedly ends in middle of line
patch: **** unexpected end of file in patch

I had to modify the patch to even get this far:

--- flac_file.cpp.orig 2007-06-07 21:44:46.000000000 +0800
+++ flac_file.cpp 2007-06-07 21:47:03.000000000 +0800
@@ -161,16 +161,176 @@
}

set_metadata_ignore_all();
- set_filename( sFilename.c_str() );
+ FLAC__StreamDecoderInitStatus s=init(sFilename.c_str() );
+ if(s!=FLAC__STREAM_DECODER_INIT_STATUS_OK) {

- State s=init();
- if( s != FLAC__FILE_DECODER_OK ) {
ERRORLOG( "Error in init()" );
}

- if ( process_until_end_of_file() == false ) {
- ERRORLOG( "Error in process_until_end_of_file(). Filename: " + m_sFilename );
+ if ( process_until_end_of_stream() == false ) {
+ ERRORLOG( "[load] Error in process_until_end_of_stream()" );
}
+
}

anything strange here?

Remember, I'm trying thr SVN version, not the ABS. the ABS works now.

Thanx

Anybody have some work completed that we all can hear? I have some stuff I've been working on on that I will share soon, and am interested to hear yours.

Just a tip. Upon afresh install ardour refused to play nice. Setting the memlock field in /etc/services/limits.conf to unlimited seems to have fixed it.

funkmuscle · 2007-08-11 14:33:40

Am I missing something on my system?
I don't have any /etc/services/limits.conf on my system.

Do I create the config file?

It's /etc/security/limits.conf

funkmuscle · 2007-08-11 16:04:16

thanx bro.

For that, all I did was change it from 250000 to 300000.

btartsa · 2007-08-13 16:29:51

oops. /etc/security/limits.conf is correct.

btartsa · 2007-08-16 05:38:10

Traverso is really nice. If you build from AUR and want to use plugins you must install the package redland from AUR. You must also comment out the first sed line in the PKGBUILD.

I have a problem with jamin, everytime it starts up it dies.
Its been doing this for a while now and Ive tried all sorts, I ve recompiled fftw and jamin, changed tmpdirs and running as new user.

I have the realtime kernel and jack running smoothly.

Does anyone else have this problem, or ideas what I can try?

Ok I started having problems with all sorts of stuff, mostly all giving alloc errors.
I checked my /etc/security/limits.conf to find my memlock was 40000.

Ive changed this to 'unlimited' (from ardour forum) and now everything is working again.
I dont know why its on 40,000, I set it ages ago from the wiki. but I dont care.. it works again

btartsa: No work here:( I've had my laptop in on repair for a month and two weeks, getting really tired of it. Anything interesting on the kernel side these days?

funkmuscle · 2007-08-20 13:46:43

does anyone know how to build a flac++ or flac dev PKGBUILD?

funkmuscle · 2007-08-31 15:48:20

Hydrogen-svn runs great on JackLab. too bad not all can get it on Arch.
I've given up on that until they release it for Arch.

on the video side of things, anyone ever got this running on Arch?

linuxvideostudio: http://ronald.bitfreak.net/lvs/downloads.shtml

if yes, got a PKGBUILD???

m00tp01nt · 2007-09-01 02:05:02

I don't know if this is stupid, but I didn't read anything about it in this thread:

I'm running kernel26rt (2.6.22.1-rt9). I was getting an xrun about every 2-3 minutes just running zynaddsubfx. I bumped up the priority setting in qjackctl as high as it could go (~89) and now I can run hydrogen, ardour and zynaddsubfx together, sync'd no problem. Zero xruns in a 45 minute session, and I have yet to receive another xrun.

So for any n00bs like me: If it seems like you're doing everything right and you still have xruns... priority should go as high as it can (limited by /etc/security/limits.conf).

Tested it here, once ALL ACPI modules are removed it gives excellent latency and on my otherwise rather weak laptop working with 5msec latency is perfectly possible (buffersize 64, periods 4 @ 48KHz).

Does getting rid of the acpi modules really make a big difference, and if so, do you know why?

funkmuscle · 2007-09-01 02:56:17

I was just about to ask for that. berkus read my mind

funkmuscle · 2007-09-01 02:59:37

only kernel26rt 2.6.21.rt8-1 on proaudio

m00tp01nt · 2007-09-01 03:49:33

I built my kernel myself. That quote is talking about the earlier kernel. I'm trying to decide if i should remove all the acpi modules/acpi support. Sorry to confuse you.

funkmuscle · 2007-09-01 14:45:09

no probs!!!

m00tp01nt · 2007-09-01 15:58:23

Blacklisting all the acpi modules didn't seem to do much for me. I can get around 23ms latency consistently. Berkus's post is making me wonder, what was the config of that 'weak' laptop? Soundcard/Ram?
I have a feeling it's my soundcard preventing me from getting lower latency. not really a problem...

As a sidenote: terminatorX + milkyTracker = gold.

Anyone know anything about lv2 / zynjacku?

funkmuscle · 2007-09-01 18:16:52

you got terminatorX working?
I't sounds like crap for me. It's doesn't scratch like earlier version at all.

btartsa · 2007-09-03 17:52:39

Regarding acpi: It is a good to totally disable acpi and apm when compiling. You may want to read this though:

Some links -->

This is the best explanation of jack's features and usage I have found:

m00tp01nt, Here is the way I am currently set up (testing):
In /etc/rc.local
chrt -f -p 99 `pidof "IRQ-5"` (my soundcard is on IRQ-5, this sets it to the highest thread handler priority)
In qjackctl options>execute script after startup>
chrt -f -p 89 `pidof "jackd"` (sets jackd just under soundcard)
In /etc/security/limits.conf
@audio - rtprio 99
@audio - nice -10
@audio - memlock unlimited

As I said this is a setup I'm testing(2.6.22rt kernel), and getting good performance. You will need chrt which is in the schedutils package in AUR...and is broken
Let me know if you want a working PKGBUILD.

EDIT: chrt is now included in the util-linux-ng package in core. The one in ABS was for a standalone version.

a working PKGBUILD would be nice.
I built that kernel and it was worse that the vanilla for x-runs so went back to the rt kernel in proaudio.
