Because we keep everything in a ringbuffer and provide exactly the required amount of data, we can use 1/4 buffers. Also increase the buffer size. We don't want to limit the buffer size to the negotiated tlength because it can be increased later. Instead scale it to the max quantum size (8192) with a max resample rate of 32.
