Re: Schiit USB audio dac

[Rita <rmorgan466@xxxxxxxxx>]

Thanks Chris for the detailed explanation.

To produce my problem, I am playing my WAV like this

aplay -D hw:1,0 /mnt/CD\ 001\ -\ Symphonies\ Nos.1\&3/01\ -\ Symphonie\ No1\ in\ C\ Op21\ -\ 1\ Adagio\ molto-allegro\ con\ brio\ \(Kurt\ Masur\).wav

And it plays.

Then after a few seconds or even a minute. 

aplay: pcm_write:1939: write error: No such device

In my kern.log

So, this happens when I goto a website in Chrome which is playing audio (Abcnews/cnn/etc...)

Chris,

I would like to use the hardware much a possible since my PC is bad and I was recommended this DAC. This amp should handle 24bit at 96. I want to get the most of out this hardware :p

The behavior is when I use chrome I sporadically get the trigger. Very likely its the Flash or other system sounds which is causing it. 

My intended use is for a HiFi music system. I have flac files and I would like to use them with my DAC and Amp.  

Do you have to do anything with ~/.asoundrc? BTW, I am not running pulse. 

I will get Guayadeque a try. I was using VLC player and selected the sound card.

This doesn't seem correct. Can you determine the specific behaviour that triggers it? For instance, maybe some Firefox plugin like Flash is getting the system sound card?

What is your intended use?

Do you want all PC sound to go through the Schiit, or do you want just music, or music and movies? Do you want to play sound files at various (native) resolutions?

For example, I use my Bifrost to play music through my stereo but I don't want system sounds to appear there. Also pulse resamples various sound sources  to a standard rate and bit depth. So I use a music player that communicates directly with Alsa - I like Guayadeque - and let pulse manage my system sound card.
