sounds like a hickup…it just stops audio for second and comes back on…is this normal?
is this why people talk about real time kernels and the like in regards to multimedia/audio creation workstations?
how do i get you my audio configure stats? I figure all this depends on you knowing what all is running on my system for audio I/O
but mainly Im curious if this is typical with openSUSE?
Depends. Sounds like a buffer overrun. How are you recording? Application?
From a CLI perspective using ‘arecord’ for example, it is possible specify the buffer size with something like
arecord --buffer-time=500000 -t wav -c 2 -f S32_LE -capture.wav
[/QUOTE]but mainly Im curious if this is typical with openSUSE?[/QUOTE]
I’m sure that it will not be openSUSE-specific, since ALSA and PulseAudio common to most distros.
I was using Reaper through Wine, I’m on a 64bit OpenSUSE system.
this is what i got after typing what you posted
arecord: main:563: value 0 for channels is invalid
That was just an example (and you may need to adjust to suit with other parameters). However, I did make a typo - it should have been
arecord --buffer-time=500000 -t wav -c 2 -f S32_LE capture.wav
More info
man arecord
Using wine all bets are off. Remember you are emulating a Windows system and running a windows exe ergo don’t expect perfect real time performance. Use a Linux app. Also like anything it all real depends on the underlying hardware. If you are short on memory and or have a lot of background stuff going it all has an effect. But don’t try to run a Windows program and expect Windows performance with real time stuff. Sometime it works and some times it does not depends on the app in question.
Of course Linux runs Windows under wine better then Windows runs Linux apps rotfl!
I was about to ask how you knew @alienbee was using wine. 
I missed the comment the earlier reply about using Reaper under wine, so I have to agree with gogalthorp’s comments.
Having said that, I note some good advice here regarding using Reaper in a wine environment
http://wiki.cockos.com/wiki/index.php/How_to_run_Reaper_in_Wine_on_Linux
Some pertinent comments…
There is no native linux port of Reaper so far, but luckily it can be made to run quite well in Wine on Linux, as can the vast majority of VST and VSTi plugins (excluding some copy protected ones). The major drawbacks being higher cpu usage, higher latency, and a slightly sluggish gui. The sad truth is that it runs much better in Windows, but on a modern multicore system it is more than usable for serious mixing work (especially at higher latencies), and for the occasional overdub at low latency while monitoring through FX. Recording high track counts at low latency, is however probably better done on Windows or OSX.
The wine-rt patch allows programs that use Windows’ concept of thread priority to gain similar functionality under Linux. It maps Windows priority levels to Linux scheduling policies. You will most likely need this if you want to run Reaper at low latency under Wine. Unfortunately this has not been included in the standard Wine source code and it’s unlikely that it will be included any time soon, thus this is one reason you might want to build Wine yourself. If your distro has already patched it’s Wine, then you can install it with the usual package manager.
ahhh…there goes that idea lol…
I was hoping to move out of windows forever!!! …turns out Reaper only works through wine for now…
ah bummer…back to windows ar ar…
I’m under a time crunch to get some recordings done and all I know how to use right away is Reaper…took me about a week to migrate most of my tools into linux , just now had a real chance to sit and try to use it for real…but that sound kept dropping every few minutes or so…
followed allot of what this article pointed out to do.
i haven’t heard any drops with audio outside of Reaper yet…so im betting its wine…i should go to the reaper forum and see if anyones been able to really use the app through wine…maybe theirs a tweak of the week that can help …thanks guys…
Well, it is recommended to use wine-rt for this purpose. I couldn’t find an openSUSE build, and it is a big ask for a new user to try, (but not impossible)
http://repo.or.cz/w/wine-rt.git/blob/wine-rt:/README.WINE-RT
Since I know you’re under pressure to get the job done, you could consider installing another distro (eg Ubuntu) that does provide wine-rt

I just did a walk through at the Reaper forum and theres a thread just recently pinned that deals with Reaper and Linux…seems like like allot of users of reaper are getting excellent results, I just really have to take a magnifying glass into the real details and compare what i did up till now and how i can back track to finding what i can do to nail down this ‘hickup’ .
I am soo new to this linux thing that I’m way in over my head …this learning curve has me drowning and learning to swim at the same time…I cant believe all the dents i put into my psychological hammer just getting this thing up and running as far as i did…I’m months into this and so close to giving windows the finger …can’t wait lol…the thread of hope says theirs a way…and yes the wine rt is for sure a great idea!! but the guys seemed to have Reaper running without them having to go there…
my next step is suppose goes into this link
My other band mate took the liberty to tweet an announcement that we would do our next release in OpenSUSE - 3 weeks till due…Ill have to come back to this tomorrow and reinstall and uninstall some packages along with tweaking through that long list of ideas on this wiki.
again thanks guys.,
I’ll be following your learning and discovery with interest. I love reading about people doing real-world stuff like you’re doing with Linux… and especially with openSUSE! So, please don’t give up.
Are you asking for all versions of openSUSE, supported and unsupported?
When you only want an answer for the version you use, please tell us which one that is.
Well you can dual boot and also you may be able to install Windows in a VM (maybe VirtualBox) and run the program there. Of course that is yet another level of complexity and learning for you
Also there are some world class audio apps in Linux audacity comes to mind.
Lots of options and it is never good to put all your eggs in one basket. Always leave a fall back position
Here are some interesting resources
http://en.wikipedia.org/wiki/List_of_Linux_audio_software#Recording.2C_editing_and_mastering
its the latest updated version…OpenSUSE 13.1 I been keeping it updated.
thanks…will keep on trying
Hello.
Bit late for your project perhaps, but in the future you might be more successful with the native Ardour.
Using JACK server requires some attention to avoid drop outs, to secure sync and so on; look at the wiki here for some good advice; http://wiki.linuxaudio.org/wiki/system_configuration it’s a bit exhaustive but to start with pay attention to /etc/security/limits.conf file, and that the user is a part of the audio group.
BTW, using wine_rt enables wine apps to run using the real time sound server JACK, so the steps above are required if you wish to proceed with Reaper also.
NB
I would recomend to start jack with qjackctl; it is a decent interface to get an overwiev of its settings, and to change them according to your needs; look at the response time display in the bottom right corner.
