This is probably going to be a super late reply, But it's not unusual in Linux for some features of DACs to not work at all even if the basic stuff does. I use a simple ISO compliant USB DAC and it's fine. Note the title of that section is "Linux low audio quality", which isn't necessarily the case. I did a search and can find no evidence whatsoever that Dolby supports Linux at all. I use an external usb dac via spidif optical into a surround amp, and the sound is better in linux than windows (in fact the usb dac just bsods in windows 7)! So linux can give very good results for sound. Or in terminal type alsamixer and follow the help instructions.Īudacious has eq and normalisation for music playback.
HOW TO USE DOLBY ADVANCED AUDIO V2 INSTALL
If the volume is still too low install qusmixer and check alsa levels. Set the normalise volume option, and use the built in equaliser to optimise the eq for your speakers. That's what smooths out the volume levels in the dolby process.Ģ) Easy fix. Not sure how you'd get compression working on a system wide level. Make sure you back everything up first.įor low volume levels might be worth installing qasmixer which will give you a gui to look at the alsa hardware levels. I had it working on mint 17.3 but ran into some problems on 18, but I think that might have been fixed now. You might get something like this working for overall system eq : Looks like there is a variety of compression, eq and psudo surround sound going on with that dolby processing.
