Ok, speaker-test works again:

,----
| [root@(none) ~]# speaker-test 
| 
| speaker-test 1.0.15rc1
| 
| Playback device is default
| Stream parameters are 48000Hz, S16_LE, 1 channels
| Using 16 octaves of pink noise
| Rate set to 48000Hz (requested 48000Hz)
| Buffer size range from 4096 to 4096
| Period size range from 2048 to 2048
| Using max buffer size 4096
| Periods = 4
| was set period_size = 2048
| was set buffer_size = 4096

And also fbxine now (kind of) works:

| To choose buffer_size = 4096

However, the sound is stuttering a lot (I guess this is a xine-lib
issue).

Nevertheless thanks Jaroslav and Clemens for your help!
