I can confirm that Millhouse's hack works with A2DP on my Sony DR-BT10CX headphones.
In the Bluetooth spec, mono audio is not handled by the A2DP profile at all. They handled completely differently, with different codecs and even different layers of the Bluetooth protocol stack. I am pretty sure Millhouse has only implemented A2DP so no mono...

Thanks - dabuplayer, that makes sense because I have played music to my mono Motorola HS850 BT headset from two of my Dell Pocket PC's in the past, and also from my desktop computer with a USB Bluetooth dongle installed. Odd that Kagu / N800 / Mplayer refuses to work that way. I have reflashed my N800 (wiping everything back to Nokia factory all) and performed all the Milhouse instructed steps again. Each time I did the Milhouse steps with great care ( I am an assembly language programmer with 30 years experience so I know how to not screw up something as simple as this). Still no sound coming thru my HS850. I believe others who claim Milhouse's trick is working for them...... oh well, I hope that IT OS2008 will have A2DP next month, and that it will allow me to use my HS850 with Skype too......that is something that is very desirable. One of the main reasons for my buying the N800 last week was to use it with Skype, GoogleTALK, and Gizmo Project VOIPs. Shame that the multimedia and VOIP Bluetooth stuff slipped by those at Nokia. They obviously were concentrating on Bluetooth GPS, cellular Internet tethering via bluetooth and Bluetooth keyboards way more than WiFi / Bluetooth Voip use. I'm not complaining.... Kagu is fantastic and so is Skype on the N800. I'll flash the OS2008 when it posts at maemo and enjoy 400mhz cpu speed hopefully next month.

Maybe A2DP support is the Easter Egg in OS 2008? A2DP support became available in the Bluez stack - mainly through the involvement of Nokia - more than 2 months ago.

dabuplayer, I think you missed my point... A mono headset does not support A2DP. SBC decoding is not trivial, and an optimized headset design does not have the power to decode SBC, and still allow a long battery life.
Since they will see the target device does not have A2DP support, phones, PDAs, PCs will probably make the connection to a voice headset like the HS850 via the headset profile. I don't think Millhouse has added headset profile support... It seems specifically targeted to A2DP only.
