hello benno :)
hope you had a good flight back to italy !
since these errors correspond to the ctl and pcm entries in
.asoundrc, perhaps you should try with one. maybe the default
behaviour when the file does not exist is broken ?
here's mine:
# cat ~/.asoundrc
pcmtype.hw {
open _snd_pcm_hw_open
}
pcmtype.client {
open _snd_pcm_client_open
}
pcmtype.multi {
open _snd_pcm_multi_open
}
pcmtype.linear {
open _snd_pcm_linear_open
}
pcmtype.mulaw {
open _snd_pcm_mulaw_open
}
pcmtype.alaw {
open _snd_pcm_alaw_open
}
pcmtype.adpcm {
open _snd_pcm_adpcm_open
}
pcmtype.route {
open _snd_pcm_route_open
}
pcmtype.rate {
open _snd_pcm_rate_open
}
pcmtype.plug {
open _snd_pcm_plug_open
}
pcmtype.file {
open _snd_pcm_file_open
}
ctltype.hw {
open _snd_ctl_hw_open
}
pcm.SBLIVE {
type hw
card SBLIVE
device 0
}
ctl.SBLIVE {
type hw
card 0
}
good luck.
