No sound

[jhansonxi]

Binary package hint: overgod

Overgod uses Allegro. In Hardy it needs liballegro4.2-plugin-jack installed and jackd running in order to get sounds. In Intrepid I can't get sounds working but I haven't performed any PulseAudio configuring yet so that may be the problem. Overgod is version 1.0-1ubuntu2 on both Hardy and Intrepid.

WORKAROUND:
If the app in questions gives this error:
"ALSA lib rawmidi_hw.c:233:(snd_rawmidi_hw_open) open /dev/snd/midiC0D0 failed: No such file or directory"
then try this:
`sudo modprobe snd_virmidi`
then go to your /dev/snd directory and create a symlink from one of your midiCXDX files to midiC0D0
For me: `cd /dev/snd && sudo ln -s midiC2D0 midiC0D0`

This looks like a duplicate of bug 445945: every Allegro-using app is broken on Ubuntu, since Allegro 4.2 is not compatible with PulseAudio.

I think it isn't a duplicate of bug 445945
Daniel Hollocher wrote in bug 445945 discussion: "yeah, I got that too, but it is a different bug. Can you open a new bug report? The error initializing sound is about the sound card not being supported at all. I think the other error is about not getting MIDI support. I tried to google it, but couldn't find anything."
So it isn't a duplicate.

Using the advice here: http://www.bigbluecup.com/yabb/index.php?topic=29886.70;wap2
I was able to get sound working in overgod. Not exactly sure what did it, if I really needed to sudo modprobe snd_virmidi or what. But I did see the midi devices, etc, setup a symlink, and it worked! I will check what a fresh boot looks like, I just wanted to get the link posted.

ok, I confirmed. Maybe this is a udev bug, maybe linux.

[Serge Hallyn (serge-hallyn)]

Is this bug still present? Is this still deemed a possible bug in liballegro4.2?

[Daniel Hollocher (chogydan)]

Im on natty, and sound seems to be working, even though the error message is still present

[jhansonxi (jhansonxi)]

Bug is still present in 10.04 (Lucid Lynx). The snd_virmidi workaround doesn't work.

I doubt a bug fix like this will be backported. You may have to use a later version of Ubuntu
