[App_rpt-users] USB fob choppy/stuttering audio

[Rob Noll]

Nothing in lsusb's output is representative of the info in the devstr line 
in the usb conf file. The device line is a single digit number as is one of 
the data points displayed by lsusb, however, the device line is commented 
out in every usb conf file I've looked at.

No problem and for future reference:


lsusb is a utility for displaying information about USB buses in the system 
and the devices connected to them.

Thanks for the reply.  I didn't wish to name the USB device as I didn't 
want to appear to be giving it a bad name if it was not the culprit. Sorry 
you feel I didn't give enough information to begin narrowing down the problem.

At a suggestion I received elsewhere, I tried HamVoIP to see if the issue 
was the same.  The audio is perfect with HamVoIP. Since I'd rather 
implement this setup on an existing Debian system instead of having a 
dedicated device, I'd like to try to figure out a way to get ASL working 
with this device.  One gentleman suggested looking into the device ID and 
making sure it was correct, however, he didn't know how to determine the 
correct information.  At any rate, some light reading has informed me that 
there seems to be some serious bad blood between HamVoIP and ASL, so since 
I've gotten to the point where the issues exists in one but not the other, 
and is therefore in the software and not the hardware (be it the cpu, 
radio, or interface), I suspect I'm better off trying to figure it out on 
my own.

Thanks to everyone who took the time to respond.

What would be very beneficial to all is when you post a question on any 
list (be it Allstar or whatever); is to identify and share as much as you 
can in terms of software you are running as well as hardware.

Example:
ASL 1.01 Raspbian Stretch Image on a Raspberry Pi 2b
Interface:
DMK USB URI
Radio:
Motorola Maxtrac
Issue:
Choppy Transmit audio

Since there are multiple combinations of software and hardware, folks 
really need to elaborate.  No one is a mind reader.  It would help if you 
are running the hamvoip image to post the question to their list at:
http://lists.hamvoip.org/cgi-bin/mailman/listinfo/arm-allstar
Since there are a number of differences between the distros and the fact 
theirs is closed, one cannot even begin to really guess at what the issues 
might be as as you cannot see what is different at a code level even if you 
share as much detail about your configs.

In my opinion each can have its place (one for more experienced users which 
to be able to roll their own/experiment and one for fairly new to Linux), 
however I would rather at some point see the two groups work together 
again.  Till such a time users just need to realize what they are running, 
and who to go to for support, else it just creates a guessing game and 
further hostility.
