BubbleUPnP great on Q!
I recently installed Cyanogenmod 10 on my Q.
The install process was quite smooth. (see the Q developer forums for tutorials)
I chose the ROM with the amp support as I have two nice Bose speakers collecting dust.
Well no longer. The Q is now my main music device in my living room.
First, I was very excited about the Cheapcast
app (quite a bit of stir about that here on the forums).
I could easily cast my music from my phone or tablet via Google Music. Worked fine, for a while.
Cheapcast, however, is nog very stable for streaming music. Hiccups, slow, connection loss.... I had to reboot the Q a lot.
I then tried Bubble UPnP
(installed on Q, some minor config) combined with Cast To UPnP/DLNA for GMusic
installed on your phone or tablet. This setup rocks and has been serving me music for the past couple of weeks.
You can try these apps for free, but there are time limits per session. Buying is well worth it.
I still preferred the original Q with the social streaming thing. But my current setup comes close: it's stable and easy. Somewhat slow in responding to actions like skip track, but it'll do.
If you have 5$ to spend on apps, give this a go. You won't be sorry.
