To troubleshoot Voice Quality issues and automate testing, I’m planning to use Asterisk as a softphone alternative (with better scripting capabilities) on a Linux 4.10-enabled Ubuntu laptop. This laptop has two audio jacks with a compatible headset.
I’m testing console channel with lines such as:
same = n,Dial(CONSOLE/default)
When I’m answering an incoming call with “console answer” CLI command, I
can read a WARNING message
“console_indicate: Don’t know how to display condition 26 on Console/default”.
At the same time, I can’t hear anything on my headset. I must say I’m a total beginner in Linux audio topic.
My questions are:
1. Which is the best way to go between OSS and ALSA ?
2. How can I list audio devices from the command line ? With aplay and arecord ? If positive, how does aplay/arecord output relate to input_device/output_device or device from alsa.conf or oss.conf ?
3. Shall I care for ” Don’t know how to display condition 26″ warnings ?
