ok, could a hack like this also help me out?
Yep, the PCM multi plugin in alsa-lib seems to be available as well.
that's encouraging. now i only have to figure that out ;) never had to deal with .asoundrc before (which is testament to the hard work of all of you, thx!).
The domain specific language in alsa-lib is not so easy to understand and control. The result affects to all of ALSA applications like pulseaudio. It's better to use alsa_in/alsa_out for the purpose to avoid unexpected influences, IMO...
From my curiousity, would I ask you extra check in system log (like journalctl -k)? ALSA Dice driver supports TCAT protocol extension, and it firstly attempts to detect it for all of devices without explicit flags (in your case). If the device doesn't support the extension, the attempt fails and we can see below log:
kernel: snd_dice fw1.0: transaction failed: timeouthere's what i see in journalctl -k when the device is being plugged in:
kernel: firewire_ohci 0000:05:00.0: isochronous cycle inconsistent kernel: firewire_core 0000:05:00.0: created device fw1: GUID 000a920404af7744, S400 kernel: firewire_core 0000:05:00.0: phy config: new root=ffc1, gap_count=5 kernel: firewire_core 0000:05:00.0: IRM is not 1394a compliant, making local node (ffc0) root kernel: firewire_core 0000:05:00.0: phy config: new root=ffc0, gap_count=5 kernel: snd_dice fw1.0: transaction failed: address error
Thanks. Now we confirm that the device doesn't support the protocol extension. (And I realize there're two cases; the device doesn't just respond, or returns RCODE_ADDRESS_ERROR.)
let me know if you need anything else.
Hm. If you hear sound with periodical noise, please report it. The dice-based device is known as one of the devices to require drivers for media clock recovery. In detail, please read the other case[1].
