Same problem here, segfault only occurs when my PreSonus AudioBox 22VSL is 
connected via USB.

Bug#991337: pulseaudio: Can confirm with another DAC/USB sound card

[Jean-Marie Favreau]

Dear maintainer, dear all,

It seems that the problem comes from the package libasound2-plugins from deb-
multimedia.
The following command to force the debian version of the package fixes the bug:

sudo apt install libasound2-plugins=1.2.2-2

Cheers

Bug#992780: libasound2-plugins: slow audio when plug/unplug external USB audio device

[Jean-Marie Favreau]

Package: libasound2-plugins
Version: 1.2.5-2
Severity: normal
Tags: upstream

Dear Maintainer,

I am using a debian testing, and tried a couple of libasound2-plugins versions 
(deb marillat versions, unstable version), but this bug is still present.
I am using an external USB audio device, and pulseaudio for usual audio usages 
(browser, player, etc). 
When pulsaudio starts, everything is fine with the audio system: when a sound 
is played, everything is ok.
Even if I unplug the usb device, the audio file is still played in the internal 
sound card with a correct bitrate.
Unfortunalely, when I replug the USB audio device, the audio file is now played 
with a slow speed, as if the bitrate was not correctly interpreted;

I tried several settings in the /etc/pulse/daemon.conf without success: trying 
to change defaultt-sample-rate / alternate-sample-rate to the same value or to 
different values such as 44100 and 48000, using avoid-resampling=yes or not.

[Jean-Marie Favreau]

Dear Maintainer,

When the laptop-mode was activated, I was getting in `dmesg` similiar messages 
every few seconds :

After a non regular time, the disk did not start again, the system was frozen 
(cannot use applications on kde, cannot log in a virtual console).
The last messages in syslog are:

I removed/purged the package. Finally, in order to reproduce the messages, I 
reinstall it, and everything seems to come back to the normal. It might be a 
configuration problem.

Sorry for these messages.

Bug#805438: plasma-pa: audio volume parameter not editable

[Jean-Marie Favreau]

Package: plasma-pa
Version: 5.4.2-1
Severity: normal

Dear Maintainer,

I have two computers with a debian/sid up-to-date system, one with the current 
bug, the other one without, and I'm not able to reproduce the bug in the other 
computer.
One the affected computer, I tried with two different user accounts, and the 
bug still appears.

The bug affects the sliders and buttons available on the audio volume 
parameters window. All tabs are visible, I can browse them, and the 
sliders/button are exactly similar to the corresponding widgets in pavucontrol. 
Even when I modify the values in pavucontrol, they are directly reproducted on 
the plasma-pa parameters.

However, sliders and buttons modification is not possible on the plasma-pa 
window (widgets are not editable, but not disabled).

Bug#856122: calf-plugins: UI not loaded in ardour (works in the standelone app)

[Jean-Marie Favreau]

Package: calf-plugins
Version: 0.0.60-4
Severity: important

Dear Maintainer,

I'm using ardour with jack, and I wanted to run the calf-plugins as LV2 plugins.
Unfortunately, even if the plugins are correctly loaded into ardour, the GUI 
cannot be loaded. Here is the message produced in the console:
suil error: Failed to instantiate UI 

 in /usr/lib/lv2/calf.lv2/calflv2gui.so

However, interfaces are working in the calfjackhost. Thus I suspect a bug in
the LV2 part of this package.
