I recently downloaded and installed QGIS 2.4 Chugiak on a Windows 7 64-bit machine with a quad core processor and 8GB RAM.

I'm having a few problems using datasets of all sizes from a network drive - the data is slow to render and there is an annoying low-pitched "beep" each time I zoom in/out. In the previous release (2.2), this network data would render almost instantly for small datasets with no sounds.

I've also noticed that opening the attribute tables for this network data is very slow. E.g. a dataset with just 91 records takes almost 30 seconds - something that was almost instant in QGIS 2.2 Valmiera.

Using the dataset on a local drive removes the problems, though this is not an option as we have several members of staff working on the same datasets and want to avoid having multiple file versions all over the place!

Have any network settings been changed from 2.2 to 2.4?

  • Do you get the sound when using local files?

  • No. The sound only occurs when using the network data in QGIS 2.4. It plays repeatedly whilst opening the attribute table until the data is displayed - generally once or twice whilst re-rendering which is completed quicker than opening the attribute table. Jul 2, 2014 at 6:19
  • Strange. Others have reported this also but QGIS doesn't do anything sound related. I wonder if it's a Qt bug of some sort.

  • Looks like the sound might be a separate issue - just installed QGIS 2.4 on my home PC and tried loading data from the network there. Same speed issues but without the low-pitched beeps whilst loading. Very slow to render / open attribute tables unless the data is on a local drive. Looks like we're sticking with 2.2 for now then until someone solves the issue! Jul 2, 2014 at 20:36
  • I wonder if the slow speeds and sound are somehow related.

Renaming the plugin "ogr_SOSI.dll" to something like "ogr_SOSI_old.dll" as Nathan suggested removed the buzz/beep sound for me. The speed issues seem to have gone too now - not sure if it was related to that or just some issues with our IT systems. All is good for now!
