Description manukakavinda2 2019-10-12 04:35:49 CEST 
I am using the appimage available from https://sigrok.org/download/binary/pulseview/PulseView-0.4.1-x86_64.AppImage 

The issue I encountered was that Pulseview only gets data for one channel when I try to retrieve two channels. the second channel stays blank. 

There were previous bug reports for libsigrok and they are marked as fixed (https://sigrok.org/bugzilla/show_bug.cgi?id=1137) but it seems like there is either an outdated version of libsigrok in the Pulseview build or something wrong with Pulseview itself. I also tried the nightly build for 2019/oct/12 GMT 0235 and it also had the bug.

Hello, please set the log level to 5 in the settings dialog, then restart PV and perform an acquisition. Then, save the log file and attach it here so we can have a look what's happening.

Thanks!

this fails around 400k samples on the first channel.

Just got on hands a DS1xxx and wanted to try pulseview.

I confirm the bug on version 0.4.2-4 (latest present in pacman as of now).

Decided then to compile pulseview (as well as libsigrok and libsigrokdecode) myself from the official repo and as of master branch of 2021-03-25 (commit 3ce5dd9a981d128085dc5ea507dd7157a87be4cb) the bug has gone and I see completely all 4 channels.
