Hello Daniel,

Here are the results of today's testing.
I don't know if they'll help in anyway, but here we go.


BOOT WITH THE UA-25EX

Trying to use aplay:

blablack at igorito:~$ aplay 10\ -\ Track\ 10-L.wav
ALSA lib confmisc.c:768:(parse_card) cannot find card '0'
ALSA lib conf.c:4241:(_snd_config_evaluate) function
snd_func_card_driver returned error: No such file or directory
ALSA lib confmisc.c:392:(snd_func_concat) error evaluating strings
ALSA lib conf.c:4241:(_snd_config_evaluate) function snd_func_concat
returned error: No such file or directory
ALSA lib confmisc.c:1251:(snd_func_refer) error evaluating name
ALSA lib conf.c:4241:(_snd_config_evaluate) function snd_func_refer
returned error: No such file or directory
ALSA lib conf.c:4720:(snd_config_expand) Evaluate error: No such file
or directory
ALSA lib pcm.c:2217:(snd_pcm_open_noupdate) Unknown PCM default
aplay: main:682: audio open error: No such file or directory

blablack at igorito:~$ aplay -D default:CARD=UA25EX 10\ -\ Track\ 10-L.wav

Second one work ok... Let it play for several minutes and it's all fine.


BOOT WITH THE FTU

blablack at igorito:~$ aplay 10\ -\ Track\ 10-L.wav
ALSA lib confmisc.c:768:(parse_card) cannot find card '0'
ALSA lib conf.c:4241:(_snd_config_evaluate) function
snd_func_card_driver returned error: No such file or directory
ALSA lib confmisc.c:392:(snd_func_concat) error evaluating strings
ALSA lib conf.c:4241:(_snd_config_evaluate) function snd_func_concat
returned error: No such file or directory
ALSA lib confmisc.c:1251:(snd_func_refer) error evaluating name
ALSA lib conf.c:4241:(_snd_config_evaluate) function snd_func_refer
returned error: No such file or directory
ALSA lib conf.c:4720:(snd_config_expand) Evaluate error: No such file
or directory
ALSA lib pcm.c:2217:(snd_pcm_open_noupdate) Unknown PCM default
aplay: main:682: audio open error: No such file or directory

blablack at igorito:~$ aplay -D default:CARD=Ultra 10\ -\ Track\ 10-L.wav

No sound...
I tried to reboot several times, unplug/replug, checked alsamixer: all
look fine to me but still no sound.
Actually, it is not "exactly" no sound: I can see the 4 front leds
flash very quickly, and I can hear a click in the speakers (with the
FX, the click is longer due to the reverb, handy to notice it!).

Using mplayer...well I don't know if I'm just an idiot or if there is
a deeper problem, but I can't get the alsa parameter to connect to the
sound card. And if I don't specify the -ao parameter, I get the same
error as aplay "cannot find card 0".

Using VLC, I can see that VLC doesn't get stuck but plays something,
unfortunately, still no sound.


In dmesg, I get:
[    3.031270] usb 2-1.2: new high-speed USB device number 3 using ehci_hcd
[    3.118175] usb 2-1.2: config 1 interface 3 altsetting 0 bulk
endpoint 0x7 has invalid maxpacket 8
[    3.118185] usb 2-1.2: config 1 interface 3 altsetting 0 bulk
endpoint 0x87 has invalid maxpacket 8
...
[   18.090854] ALSA mixer.c:796 usb-audio: set quirks for FTU Effect

[   18.107831] ALSA mixer.c:787 usb-audio: set quirk for FTU Effect Duration
[   18.109496] ALSA mixer.c:796 usb-audio: set quirks for FTU Effect
Feedback/Volume

The first error message is "ok" I far as I remember, and the second
message shows the detection of the FTU - all look fine to me...



IN BOTH CASES, FTU AND UA-25EX

Starting jack result in an immediate freeze of the system.


If there is anything else I can provide to you, let me know.
Hope all this help somehow!

Aurélien
