I don't really think the problem is the network but the audio decoding.

How cool is that? With lower bandwith the audio works! In the code I can see on
sound.c:
<span class="quote">> delay_val = main_channel_client_is_low_bandwidth(mcc) ? 0 : 1;
> if (setsockopt(stream->socket, IPPROTO_TCP, TCP_NODELAY, &delay_val, sizeof(delay_val)) == -1) {</span >
...
But I don't really think it would be related to your problem.

I have played with real-time audio decoding on Android and I got really
frustrated with the outcome. That was 3 years ago so I hope it is much better
now. That being aSpice is not really maintained by us so I'm not sure how we
can help with this client.
If this client is based on spice-gtk, one could play with SPICE_DISABLE_CELT or
SPICE_DISABLE_OPUS but I'm not aware of other ways to change audio
configuration.</pre>
