USB soundcard not recognised (edirol/cakewalk UA25)

[Vanessa Lewis]

I am using an Edirol/Cakewalk UA25 USB soundcard with my Windows partition, which works.
I have also used the UA25 with Ubuntu 7.10, which worked.
I upgraded to Ubuntu 8.04 and the audio does not immediately work through this soundcard as it did with 7.10
I then did a fresh install of 8.04 rather than an upgrade and it did not solve the problem

The command "speaker-test -c2 -D plughw:UA25 -twav"
returns the result "Playback device is plughw:UA25
Stream parameters are 48000Hz, S16_LE, 2 channels
WAV file(s)
ALSA lib pcm_hw.c:1207:(_snd_pcm_hw_open) Invalid value for card
Playback open error: -19,No such device", repeatedly.

I have read bug report 111635 but although the problem is similar in my case Ubuntu does not appear to have recognised the sound card at all.
I've also seen a few related problems on the forums but I haven't found any answers that have worked in this case.

Thank you for taking the time to report this bug and helping to make Ubuntu better. This bug did not have a package associated with it, which is important for ensuring that it gets looked at by the proper developers. You can learn more about finding the right package at https://wiki.ubuntu.com/Bugs/FindRightPackage. I have classified this bug as a bug in linux.

The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the upcoming Intrepid Ibex 8.10 release. As a result, the kernel team would appreciate it if you could please test this newer 2.6.27 Ubuntu kernel. There are one of two ways you should be able to test:

1) If you are comfortable installing packages on your own, the linux-image-2.6.27-* package is currently available for you to install and test.

--or--

2) The upcoming Alpha5 for Intrepid Ibex 8.10 will contain this newer 2.6.27 Ubuntu kernel. Alpha5 is set to be released Thursday Sept 4. Please watch http://www.ubuntu.com/testing for Alpha5 to be announced. You should then be able to test via a LiveCD.

Please let us know immediately if this newer 2.6.27 kernel resolves the bug reported here or if the issue remains. More importantly, please open a new bug report for each new bug/regression introduced by the 2.6.27 kernel and tag the bug report with 'linux-2.6.27'. Also, please specifically note if the issue does or does not appear in the 2.6.26 kernel. Thanks again, we really appreicate your help and feedback.

I have tested the alpha4 for ubuntu 8.10 and there is no longer any problem with the SP25 / UA25 soundcard in this release.
Very much looking forward to the main release of Intrepid!

It should be noted that in the process of experimenting with the soundcard in different ubuntu versions I have realised I missed something the first time round and have managed to make the 8.04 version recognise this soundcard. However it only seems to work when the 'advance mode' switch on the soundcard is set to the off position (meaning that the advanced features of this soundcard could not function), whereas 8.10 recognised it in all instances.

Thanks very much

Hi Leann,

I am experiencing the same problem with my Edirol UA-25 sound card in Ubuntu 8.04 Heron, and can confirm that it indeed works somewhat in Ubuntu 7.10 Gutsy (Live CD - Advanced switch set to off) after selecting USB Audio under Sound Preferences.

I am willing to install and test the 2.6.27 Ubuntu kernel - is there an easy way to install the linux-image-2.6.27-* package?

Thanks!

[Tero Gusto (tero-gusto)]

I just installed Ubuntu 8.10 Intrepid Ibex (Alpha 4) on a Fujitsu Siemens Amilo pro V1000 laptop, which automatically updated itself to kernel 2.6.27-2-generic.

I can confirm that there is sound via PHONES and that I can record both guitar(Input 2/R) and microphone(Input 1/L), with advanced set to either "ON" and "OFF". I haven't tested if MIDI works yet, maybe later.

To reduce the options from the drop downs under Sound Settings, I disabled the internal sound card (onboard Intel AC97 card) by editing /etc/modprobe.d/blacklist:
# turn off internal soundcard
blacklist snd_intel8x0
blacklist snd_ac97_codec
blacklist snd_ac97
(From http://ubuntuforums.org/showpost.php?p=1370551&postcount=8)

In Sound Settings, the dropdown now looks like this, marked with a cross if clicking on Sound works:
x Autodetect
x EDIROL UA-25 USB Audio (ALSA)
x EDIROL UA-25 USB Audio (OSS)
x EDIROL UA-25 USB Audio (OSS)
  ALSA - Advanced Linux Sound Architecture
  OSS - Open Sound System
x PulseAudio Sound Server

Maybe it isn't important, since the sound card seems to work fine, but I tried the sound test for fun, With advanced set to "ON" or "OFF", doesn't matter:

$speaker-test -c2 -D plughw:UA25 -twav

speaker-test 1.0.17

Playback device is plughw:UA25

Thanks for testing and the updates everyone. Vanessa, since you are the original bug reporter, I am going to mark this "Fix Released" for Intrepid. For anyone else still experiencing issues or different issues than what was originall reported, please open a new report. It is helpful to the kernel team if bug reports target once specific issue against a specific set of hardware. Thanks.
