Title: MC20 crashes when using convolution [Solved]
Post by: matze81479 on January 23, 2015, 02:24:06 pm

Hi,

when using DSP Studio -> Convolution, MC20 Linux crashes in most cases when switching to an audio file with another resolution:

(1) Playback of 96 kHz .flac files -> OK
(2) Switch to another 96 kHz album -> OK
(3) Start playback of a 44.1 kHz .flac file -> MC20 crashes

Typical error messages on the terminal window after crashing are (sorry, it's in German):

Quote

*** Error in `mediacenter20': free(): invalid pointer: 0xeefca208 ***
Abgebrochen (Speicherabzug geschrieben)

or

Quote

*** Error in `mediacenter20': corrupted double-linked list: 0xeee3e7c0 ***
Abgebrochen (Speicherabzug geschrieben)

Without Convolution, everything works fine. Also when starting MC20 and playing only tracks of the same sample rate. And it does not matter which sample rates you choose.

My system: Notebook with
- Ubuntu 14.04.1 64bit (Partition 1) and Ubuntu Studio 14.04.1 64bit with Low-Latency Kernel (Partition 2)
- MC20 Linux Build 20.0.58

Any ideas?

Regards,
Matthias

Could you provide the files you're using for convolution as well as a link to this thread to bob at jriver dot com?

Thanks.

Can't reproduce this.
What are your audio settings for track change?
Are you stopping between the first album and second or just double clicking on something else?

Hi Bob,

I've tried it with every possible setting for track change. MC20 crashes with all of them. Usually it crashes immediately after changing to an album with another resolution, sometimes after one or two further tracks.

And it crashes also after stopping, waiting, and starting the next album.

First I thought that it could be related to my Antelope DAC. But it crashes also with the Notebook's internal audio device.

And it's not only a Linux issue - it crashes also with Win7 64bit and MC19.

Regards
Matthias

But it's fine if you don't use convolution?

We've got a possible fix coming next build.  Hang tight, and please let us know (because we couldn't reproduce the crash, but found something a little suspicious).

Yes, without convolution everything works fine.

Thanks. I'm looking forward to test it.

Hi Matt,

the fix works  :) Starting with Build 20.0.63 there were no more crashes. Thanks a lot !!!
