after one problem, I have a second... So, my computer configuration is:

  • Operating System: Dual Boot Windows 10 and Debian 8 Jessie (64 bit)
  • Motherboard: Asus Z170 PRO Gaming
  • Graphic card: Nvidia GTX 1080 (Reference/Founder Edition)
  • Processor: Intel I7-6700K

    Memory: 16 GB - 2 x 8GB 3200 mhz (probably crucial, I forgot...)

  • Hard Discs: SSD m.2 512 GB Liteon (NVMe, Debian 8 Jessie) SSD MX300 1050 GB

    (Windows 10 installed)

  • SSD OZ SATA 2 30 GB (nothing already installed, but I will add this space

later to my Debian for testing, sandbox, etc...)

  • Monitor: Dell U3415W (21:9) - SPEAKERS BUILT IN (the only)

I have no sound... I tried few solutions provided on ubuntu/debian forum however without success. I have below error messages:

I tried pulseaudio --kill, start etc, and I'm not able to see any changes.

I'm using my monitor dell U3415W as an audio (audio built in), however in the audio setting.

When I run the pavucontrol, for Output Devices, I can only see 2 entries:

  1. "HDA Nvidia Digital Stereo (HDMI)": Port: HDMI / DisplayPort (unplugged)


  1. "Built-in Audio DIgital Stereo (IEC958) Port: Digital Output (S/PDIF)

When I'm going to "Configuration" Tab, I can see that for HDA Nvidia (1) everything is "unplugged".

When I'm pressing volume up button on keyboard occured Digital Output (S/PDIF).

My monitor is connected to the PC via mDP.

PS: It's not working via root and standard user.

Best Regards.

  • (1) According to the second last line of pulseaudio -D, it's already running (verify with ps axu), so you don't need to start it. (2) If you haven't installed it, try using the proprietary nvidia graphics driver, in the hope that it can drive the HDMI output correctly. (3) When you test audio, make sure in pavucontrol it uses the right output, even if it is marked "unplugged". – dirkt Feb 24 '17 at 18:01
  • Dirkt, I already installed nvidia graphic drivers as my first problem was incorrect resolution, I don't want to mess with it again if it is not necessary. For: "make sure in pavucontrol it uses the right output, even if it is marked "unplugged" - I will check that at the morning, however all entries are (HDMI), but my monitor is connected by Mini Display Port cable not a HDMI, so it shouldn't be visible as "mDP" instead of "HDMI"? – Veroker Feb 24 '17 at 23:19
  • Ok, let's figure out the driver. Do aplay -l, you'll see a list of card X: ... , device Y .... Pick X and Y for your mDP port (or all possibilities you see), Look for a file /sys/class/sound/pcmXDYp (with numbers for X and Y). Do udevadm info -a /sys/class/sound/pcmXDYp | grep DRIVER. If the output doesn't make sense, put output of aplay -l and udevadm ... without grep into a pastebin and let me have a look at it. HDMI and DP are similar enough that they can use most of the same hardware, so it'd show up as an HDMI port. – dirkt Feb 25 '17 at 7:39
