[Partially solved] No sound with USB DAC
Posted: Thu Mar 14, 2013 10:58 am
Hi everybody !
I recently acquired an Audinst HUD-mx2. Most usb DAC in this price range are plug-and-play and use VIA, and his little brother, the HUD-mx1, is plug-and-play too, so I expected it to bee. But it's not really the case.
I mean it's correctly recognized by the system, appeared in Parameters -> Sound or pavucontrol and when playing a song (or any other sound from any other application), the indicator turns to green, meaning the device is active and receives a well PCM signal. But no sound comes from my headphones ...
I downloaded Live-USB of Ubuntu 12.10 and Fedora 18 and tried on an other PC running LinuxMint 13 Maya, and the problem is exactly the same. It's works fine on Windows 7
Here are some technicals (or not) informations :
I'm under LinuxMint 14 Nadia 64bits, cinnamon Edition. I use pulseaudio and Decibel Audio Player (but the result is the same with vlc or when playing video on youtube).
The Windows 7 is 32bits.
The HUD-mx2 uses a VIA Vinyl EnvyUSB 2.0 Audio Controller which is recognized by the kernel :
When playing a song, the device is pretended to be correctly used :
I also mention that I tried my father's VDAC II and a NuForce Icon 2 and they both work fine, on LinuxMint 13, 14 and Windows 7.
I don't know what other information I should give. If you need, please ask.
Thanks a lot for helping me
