Now, I connected USB sound card and it shows the sound
card as follows,
cat /proc/asound/cards
0 [PCH ]: HDA-Intel - HDA Intel PCH
HDA Intel PCH at 0xf7d30000 irq 35
1 [HD ]: USB-Audio - USB Sound Blaster HD
Creative Technology USB Sound Blaster HD at usb-0000:00:14.0-2,
full speed
After starting jack server using qjackctl, opened terminal and
ran the following cmd
$zita-a2j -d hw:HD -p 1056 -v
Then in qjackctl connected the graph as shown in the attached picture.
USB sound card input (line-in) is connected to an audio output from other PC.
But I can't hear the audio using zita-j2a.
I mean audio was not heard in PC where zita-j2a is running.
Anything wrong in the connections, how to debug and check why
no audio is heard.
Starting jackd from the command line is preferable to qjackctl for debugging.
Use jack_connect to make connections.
Use jack_disconnect to break connections.
Use jack_lsp to show existing jack connections.
Read man pages:
man jackd
man jack_connect
man jack_disconnect
man jack_lsp
