Edirol UA-25EX not recognized

[kb19]

Hey folks, I have just purchased this audio interface and cannot, for the life of me, get it to work. It shows up under lsusb but not when I do the whole cat /proc/sound/alsa (in which case only my onboard sound shows up). Does anyone have any suggestions? I read that this audio interface worked with ubuntu and it's really a pain to get it set up. I'm running Ubuntu 8.04.

oh and it does not show up when I do System - Pref - Sound

thanks in advance

Hi,

I [...] cannot, for the life of me, get it to work. It shows up under lsusb but not when I do the whole cat /proc/sound/alsa (in which case only my onboard sound shows up).

Does it work already?

I'm curious whether I should by this device, too.

Same problem here. I thought I read somewhere that the ua-25 worked, but no success... Too bad, I'll just have to cope with a little less sound quality when I'm using Ubuntu...

Hi all,

I too have just bought a UA-25EX, with only limited success so far (I'm running Debian with a 2.6.21 kernel but I thought my experiences might be useful to you).

In standard mode (set by flicking the switch on the back of the box) the UA-25EX is recognised and I can playback and record using ALSA and JACK, but only in 16 bit, 44.1KHz and no MIDI, due to the UA-25EX's limitations in standard mode.

In advanced mode the unit is recognised as a USB device, but not by ALSA. My current thinking is that the ALSA driver, snd-usb-audio, doesn't recognise the new product ID for the UA-25EX, which is different from the UA-25.

I'll post back any further successes here, as time permits.

Cliff.

Hi all,

Same problem here, only able to get Ubuntu to recognize the UA-25EX if the "Advanced Driver" switch is off.

Although, I found out this page about the UA-4FX and a really similar problem with the "Advanced Driver":
http://alsa.opensrc.org/index.php/Ed...d_mode_to_work

May be it is "as simple as" creating a similar patch for the UA-25EX.

I'll have a look as soon as I have some free time.

Cheerio,
Aurélien

Hey guys,

I modified the patch from the link in my previous message.
I made the soundcard work, but may be it needs some improvements...

Add Alsa support for Roland Edirol UA-25EX in Advanced mode
(for MIDI support and sample rates of 48 kHz and 96 kHz)
