Flushing DNS cache?

I'm experiencing a problem with Spotify web player, as it isn't playing anything at all. One of the solutions I've run into advise to "flush DNS cache".

Ho to do that under Arch?

"... being a Linux user is sort of like living in a house inhabited by a large family of carpenters and architects. Every morning when you wake up, the house is a little different. Maybe there is a new turret, or some walls have moved. Or perhaps someone has temporarily removed the floor under your bed."

Re: Flushing DNS cache?

Depends on your network configuration, what are you using? If you didn't knowingly set this up, the answer is likely to be you are not caching a DNS. So you should elaborate on the actual issue. What does "isn't playing anything at all" mean exactly? Does the progress bar not continue? What's your audio setup? What are the outputs of 

sudo fuser -v /dev/snd/*
#If using pulse
pacmd list-sinks
pacmd list-sink-inputs

Re: Flushing DNS cache?

I didn't set DNS caching, at least I don't remember doing this.
The play button can be clicked, but nothing happens, there is no sound, no progress etc. Spotify native Linux client build from AUR works perfectly, although I'm not satisfied with the sound quality (s16le, 44,1kHz only).
