I just installed r121 on my 860. A bit of a pain getting here, but it's got some nice stuff. I managed to get my sound working after xmms gave me the 'Cannot load esound output plugin' error by first installing the esound package from the main feed, and then running alsamixer & making sure both the 'Output Mixer Hifi Playback Swit' and the 'Output Mixer Line Bypass' are NOT muted.
As well, I found that unless I turned the 'Speaker Function' to off, it would play on the speaker as well as the headphones. I guess I'll have to turn that back on if I actually want to use the speaker (I assume for alarms). I'll have to do some more testing.
Does anyone know where alsamixer savaes it's settings? I'd definitely like to back that file up!!
