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@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@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@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@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 Feedback/Volume [ 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!
