IPC2 ("IPC-D2X2-C3337NL-H500-WB-XLM-FM4U-BMint Desktop" — what a mouthful!). I upgraded it to 16GB RAM and a 512GM SSD. I was disappointed not to be able to obtain the i7 version
I got a second monitor today and realized one more reason why I wanted the i7 — it has 2xHDMI and 1xDisplay port and my "MintBox2" only has one of each.
Anyway, the two (Samsung) monitors are connected:
- 23" monitor — HDMI to DVI adapter then DVI cable to the monitor.
- 24" monitor — Display Port to HDMI adapter then HDMI cable to the monitor.
The 24" monitor has HDMI, DB-15 (VGA?) and audio connectors.
I am running Linux Mint 17 - XFCE (completely up to date).
I have the audio-out from the IPC2 plugged into an external amplifier (an older Nakamichi receiver). This worked excellently and I was very happy... until I connected the second monitor (the 24" one with the audio connector). At that point I got no sound.
I guessed what had happened. When I unplugged the cable from the IPC2 and plugged it into the audio-out from the 24" monitor (and cranked up the volume), I got the sound. BUT it is... awful.
So it looks like the IPC2 is detecting the presence of an audio line and turning off its audio-out jack. This is just a guess, but that would account for my results.
Does anyone know a way I can force the audio to go to the IPC2's audio-out jack?
There are either defects in Linux Mint 17 (or Pulse Audio) OR things are rather obscure — I suspect the former.
Here is how I resolved the issue (I now have my nice sound back again!):
- Launch PulseAudio (can be done from the PulseAudio Volume Control if you have that installed in a panel; otherwise, from the Whisker Menu or whatever menu you use — probably under "Multimedia").
- Click on the "Configuration" tab.
- "Built-in Audio" will show as "Digital Stereo (HDMI) Output", possibly one of the variations. Change that to "Analog Stereo Output + Digital Stereo (IEC958) Input".
- Launch a terminal window and enter the following command:
(enter your password if prompted for it). This kills (stops) the pulseaudio daemon which restarts within a few seconds.
Code: Select all
sudo pkill pulseaudio
