Re: [Alsa-user] Schiit USB audio dac
Chris, Good news. I moved the USB from front of PC to back of PC and I don't get flapping. I am using VLC which I select the audio device and I get no flaps whatsoever. My PC is a HPAMD 64bit. It does not have external hub. My USB keyboard is still attached :-) Running : kernel, 3.11.0-19-generic. alsa-base(1.0.25+dfsg-0ubuntu4) VLC media player 2.0.8 Twoflower (revision 2.0.8a-0-g68cf50b) I am still playing music from a different HDisk partition (ext3). BTW, pulse audio is running on my distribution. I hope thats not down sampling my wavs. On Fri, Apr 18, 2014 at 9:05 PM, chris hermansen clherman...@gmail.comwrote: Rita, list, On Apr 18, 2014 1:45 PM, Rita rmorgan...@gmail.com wrote: hi Rita, could you tell us a bit about your PC?

It does not have external hub.

As long as it works! BTW, pulse audio is running on my distribution. I hope thats not down sampling my wavs. A few thoughts for you. You might want to turn your .wav files into .flac files. Uses less space, accomodates tags, etc. No loss of quality though I have read claims that .wav files sound better (not going there myself). Also, if you want all your sound to go through the Schiit you probably want pulse to control it. As far as I know (anyone reading this who knows better please correct me), pulse picks one target output resolution and resamples everything to that. So if your use is mostly 44.1kHz/16bit, then you should set pulse to use that as its output so that your music doesn't get resampled. If you are like me, and you have a bunch of files at varying rates and bit depths, then you probably don't want to use pulse; you probably want a music player to talk right through to Alsa. I am not sure about getting pulse and a music player to share the same device; I guess you just have to try. It may be possible to use pure Alsa with mixer enabled and push pulse out of the way; if you want that, I guess you just have to try! Whatever you learn, please consider writing about your findings back on this list so that others can learn from your experience!

I have never had to fuss with .asoundrc I will get Guayadeque a try. I was using VLC player and selected the sound card. For me, Guayadeque is a great solution for my laptop + AQ DragonFly + headphones. With Guayadeque you select View Preferences Playback There is an output device combo box. You set it to Alsa and then enter the name of your device. For example with my DragonFly I use plughw:CARD=DragonFly,DEV=0 Ideally you should use hw to avoid any transformations, but in my (limited) experience cards tend to support some but not all relevant bit depths and therefore plughw is often needed. You can experiment with this best using aplay - get some sample files from the 2L website for instance, convert them to wav, and then see if you can play back both 16bit and 24bit wav files through hw. If so, great, you are on your way; if not, you need plughw. Also, I may be wrong but I think the Modi does not support 176.4 nor 192 kHz files. If you expect to play these, you may also have to use plughw to force on-the-fly downsampling. Anyway the thing to do is try and of course please report your results back to the list so that others can benefit from your experience! I should also mention that a better solution for me for the desktop + Bifrost + hi-fi is mpd plus various different clients, both on the desktop machine itself and on my Android phone. The ability to control the music queue by remote is quite nice. mpd, like Guayadeque, can easily be configured to pass files through directly to Alsa. However, if you intend to control your music queue through your desktop, Guayadeque's UI and features seem to me to be the best available. Its smart playlist is particularly good, at least with my music collection; and it comes with a great list of internet radio stations.

Re: [Alsa-user] Schiit USB audio dac
i just tried the DAC in a macbook pro. The cable and audio works. so we know the DAC and the cable works.

The time between disconnects seems to vary from 1 to 3 seconds, so it sounds like something flaky. Can you try it in a different port on the Ubuntu machine? If that does nothing, then it's back to Chris's suggestion of a newer kernel...
