Hi folks. I face difficulties to get my PCM2707 going. I tried all kind of stuff. Of course I got thousands more options - not now.
I don't think it is that easy to combine a 16 and the 24 bit devices. (I tried plug etc.). Jive_alsa crashes all the time during startup. When starting it manually I can see the error codes. Some of the tests ended up so bad that the Touch died with a kernel crash. The only thing I managed to achieve so far is that I can run "default" config ( "card 1" in asound.conf) at 24bit with my 16 bit DAC and Johns setup. But that generates clicks here and than. What a pity that the jife_alsa startup parameters seem to be hardcoded. It would make my life much easier if I could assign flexible parameters ( e.g. device and bitdepth) through a config file somewhere. Should be a No-brainer for the designers to implement something like that. ;) However: I managed quite easily to run aplay with data from SD-card on my USB DAC. Works flawless and sounds great - really good. I also had a problem to get my Opticis optical USB going. It usually comes up as a hub. My guess that's not manageable by the current embedded Linux - a combination of a hub and a snd device. In any case I consider it a must-do for the Logitech folks to implement that usb-audio support - at least to a certain extent. This lifts the Touch up into a different league. And opens up a complete new and huge target group. I 'd guess that the majority of PC-Audio people got USB DACs at home. I am not sure if they would switch to the Touch if they would have to switch to SPDIF. The implementation efforts will cost close to nothing for just making the driver available - my guess. However, Logitech could not guarantee device support beyond Alsa device support. That must be one of the key obstacles and reason not to go for it. In this case a "community plugin" would be needed. Logitech just would have to fulfill our "little" wishes, which will cost even less. John: You said you're working on a plugin. Do you think Logitech would be open to discuss "little" changes to set a proper base for such a plugin? The two issues from my point of view are "card numbering" to get rid of the rather random numbering and "flexible configuration of jife_alsa start parameters to be able to change e.g. the device id as defined in asound.conf and bitdepth. Another nice-to-have feature would be that hub-support. And: The new Alsa usb-audio driver 1.0.22-B is lighyears ahead ( much wider device support, asynch USB, 192khz, better USB handling...) of the old stuff on the Touch. Hopefully one day we'll see a 2.6.33-rt and 1.0.22b Alsa on the device.
