I have an Acer Aspire One 751h which has a 1.33GHz Intel Atom Z520 CPU.
It seems unable to decode radio streams that run at 128k, all BBC radio streams stutter hopelessly whether I use a dedicated application (radiotray) or try listening using iPlayer in Firefox.
Running top shows radiotray using around 60% of the CPU with pulseaudio using 10% or so, that doesn't leave much to spare!
Do I really need a faster computer to listen to radio on line? I'm pretty sure it's not a bandwidth problem, the on-line BBC iPlayer bandwidth check tells me I have enough bandwidth to play HD television.
Are there any audio/radio apps out there which specifically aim at using as little CPU as possible?
