Using zynaddsubfx causes 100% CPU usage

[Nicola Jelmorini]

Binary package hint: zynaddsubfx

Hi,
I use Ubuntu Edgy, and I have just installed the zynaddsubfx 2.2.1-4 package.

All function well, but when the program is running, the CPU goes to 100%.
I don't use Jack, but only OSS output and no midi instruments.

When I start the program from a terminal I receive these messages:
========================================

ERROR: Cannot make a jack client (possible reasons: JACK server is not running or jackd is launched by root and zynaddsubfx by another user.).

Using OSS instead.

I have just downloaded the LiveCD Feisty Herd3 for testing, and I have installed this package.
I can say you that now the CPU is no more 100%. Now the use of the CPU is very low (0% - 2%).
I can think now that this bug will be resolved with Feisty release.

bug rejected because with Feisty is resolved.

Here on ubuntu 9.10, it uses 100% cpu time, but does work

[Maxim Levitsky (maximlevitsky)]

when using padsp, it even emits sound...
it just always uses 100% cpu

[Maxim Levitsky (maximlevitsky)]

I found that I didn't have oss emulation in the kernel. When I added it, problem disappeared

[Maxim Levitsky (maximlevitsky)]

It really works now
I am closing it for now, reopen if you see this again
