[Résolu] DAC audiophile Micromega MyDAC

Flyerjet · Le 05/05/2020, à 17:59

Bonjour à tous,

Depuis quelques semaines, j'ai fait le grand saut, et suis passé en 100% Linux sur ma machine.
J'ai opté pour Ubuntu 20.04.

J'ai été très agréablement surpris par la prise en charge automatique et instantanée de tous mes matériels... Sauf un (le dernier que j'aurai imaginé poser problème) : mon DAC audio.
En effet, Linux est réputé dans le milieu audiophile, notamment pour sa prise en compte de DAC en USB classe 2.
D'ailleurs, il y a déjà quelques années, j'avais réussi à faire fonctionner ce même DAC sur Raspbian : il ne me serait pas venu à l'idée qu'un périphérique fonctionnant sur une "petite" distribution ARM ne fonctionne pas sur Ubuntu quelques années plus tard.

Le DAC en question est un MyDac de la marque Micromega.

Il fonctionne parfaitement (et sans que je n'ai quoique ce soit à faire) en USB classe 1, mais dès que j'essaie de passer en classe 2, il n'est plus reconnu.

Voici le résultat de dmesg :

J'ai passé plusieurs heures à faire des recherches, et les résultats ne m'aident pas vraiment :

Plusieurs forums évoquent le fait que le MyDac ne fonctionne plus en classe 2 sur Ubuntu après la 12.04
Certains concluent que ce DAC ne doit être utilisé qu'avec Windows ou Mac
J'ai trouvé la confirmation que je ne suis pas fou : de nombreuses personnes utilisent bel et bien ce DAC en classe 2 avec des Raspberry Pi

Je vais donc fonctionner en attendant en classe 1, mais je trouve frustrant de me servir de ce matériel que de manière si limitée, et surtout de savoir qu'il est bel et bien compatible Linux puisque certains l'utilisent sur des distributions plus contraintes et confidentielles.

Si vous avez des suggestions, je suis plus que preneur !

Salut,

Peux-tu donner l'ensemble des lignes retournées par :

dmesg | grep usb

Avec ton DAC débranché puis branché donne le retour de :

lsusb

Si tu utilises un hub usb (multiprise usb), essaye sans.

A+

C'est bizarre, chez moi l'interrupteur USB AUDIO CLASS est sur 2 et je n'ai pas de message d'erreur,
avec Ubuntu Mate 16.04.
Avec le DVD d' Audiophile Linux ça fonctionne aussi.
Cordialement,
Guy

Si tu utilises un hub usb (multiprise usb), essaye sans.

Mon DAC est branché en direct sur le PC.
J'ai essayé sur un port USB3 de la carte mère, puis sur un port USB3 d'une carte d'extension PCIe : même résultat.

C'est bizarre, chez moi l'interrupteur USB AUDIO CLASS est sur 2 et je n'ai pas de message d'erreur,
avec Ubuntu Mate 16.04.
Avec le DVD d' Audiophile Linux ça fonctionne aussi.
Cordialement,
Guy

Bizarre en effet...
Ca me donne un peu d'espoir d'y arriver

Oh que j'ai honte !!!!
Pour voir l'interrupteur de mon DAC, je dois déplacer tout un meuble, et j'ai fait tellement de tests que j'ai fini par perdre le fil.

Il se trouve que mon DAC fonctionne parfaitement en classe 2, et que c'est en classe 1 qu'il ne fonctionne pas.
C'est toujours mystérieux, mais à la limite ce n'est pas très embêtant...

Donc, pour info, en classe 2 :

Ca me semble donc excellent !

Je suis vraiment navré de vous avoir fait perdre du temps.

Merci beaucoup pour vos réponses !!!

Je suis content que ça marche !
Mais comment fais-tu pour lire un SACD ? Ça marche sur mon lecteur de CD de salon, mais avec l'ordinateur, je n'y arrive pas.
Cordialement,
Guy

Flyerjet · Le 09/05/2020, à 19:06

Pour être tout à fait franc, c'est un album que l'on m'a passé en format FLAC.
Je ne sais pas comment il a été rippé (je sais qu'à une époque certains utilisaient une PlayStation3).

Je ne possède pas de SACD physiques : la majorité de ma bibliothèque haute résolution provient de la plateforme française dont le nom commence par Qo et termine par buz (et, je dois bien avouer, quelques rips que l'on m'a donné, mais vu les carrières des artistes concernés, cela ne me pèse pas trop sur la conscience).
Mais je comprend bien que quand on a acheté le SACD, on n'est pas enchanté à l'idée de racheter l'album en numérique.

EDIT : j'ai fait une rapide recherche et suis tombé sur cet article très intéressent : https://www.journaldulapin.com/2018/07/18/rip-sacd/
Peut-être possèdes-tu une platine blueray compatible ? Sinon, il semblerait qu'on en trouve pour une cinquantaine d'euros. Selon la taille de ta collection de SACD, cela peut valoir le coup ?

Bonjour,
Je viens d'acquérir un Micromega MyDAC. J'ai essayé les tests indiqué plus haut et l'un d'entre eux affiche des erreurs. Peut-être que vous pouvez m'aider ?

Est-ce que tu as bien mis le petit interrupteur derrière sur 2.0 ?
Est-ce que tu as essayé tous les ports USB de ton ordinateur ?
Cordialement,
Guy

bonjour gl38,
oui, j'ai testé tous les ports et l'interrupteur est sur 2.0
pour info, je branche des enceintes actives M-AUDIO AV 40 directement sur le MyDAC

sur https://www.xcore.com/viewtopic.php?t=6181
j'ai trouvé le diagnostic suivant:
This normally is due to a Signal problem. Check your PCB Design. Possible sources of error can be:
USB Bus on your board has not an impedance of 90 Ohms
Your Power Supply is not blocked properly with capacitors
you routed something directly under your USB bus (steep impedance changes)
do you have a GND plane (without any routings)
your lines length differ more than 4mm

Est-ce qu'il n'y aurait pas un problème de compatibilité d'impédances ?
Voila ce que je trouve à ce sujet sur
https://www.son-video.com/article/encei … le-av30-v2

Puissance dynamique : 10 watts CC, par canal en 4 Ω
Impédance d'entrée : 10 kΩ asymétrique, 20 kΩ symétrique

Merci de ton aide,
Cordialement,
Brunodd

Que donne lsusb avec le Mydac débranché ?

Mon PC qui n'est pas tout jeune a des ports usb 1.1 et 2.0.
J'imagine que l’interrupteur sur 2.0 veut dire que le Mydac attend un port usb 2.0 .
Sauf erreur de ma part, il y en a chez toi, ceux qui sont marqués "Linux Foundation 2.0".
Le Mydac est sur la ligne

Bus 003 Device 046: ID 26f2:0200

Moi j'ai

Bus 001 Device 004: ID 26f2:0200 MICROMEGA  MICROMEGA MYDAC

qui indique qu'il est bien reconnu.
Cordialement,
Guy

brunodd · Le 19/04/2021, à 17:36

oui, la ligne est là, mais pas le nom du MyDAC,
pourtant il est reconnu :
https://ibb.co/7CsKVvG

j'ai deux ports USB 2.0 et 2 ports USB 3.0
branché sur l'un ou l'autre, le bug demeure
mais ça fonctionne...
Cordialement,
Bruno
