MuseScore no sound

[Eggbertx]

I know this has been asked before, but for other vesrions of fedora and other distros. I am running Fedora 12. I installed MuseScore, and it runs fine on Windows XP, but in Fedora 12, even with the ALSA Audio Device set to default, hw:0, or hw:0,0 I still get no sound. Nothing happens when I press play. Why is it that I have to jump through hoops of fire to get anything with MIDI to work in Fedora?
When I run MuseScore from the terminal, these errors pop up:

Alsa_driver: Cannot open PCM device hw:0 for playback.
init ALSA audio driver failed
init ALSA driver failed
init audio driver failed
sequencer init failed

That is a "fair enough" type of question and here are some possible answers:

- There is not enough music geeks that use Fedora, consequently there is not enough functioning software.
- Fedora documentation is spread all over and there is not one place to look for all of it so it is possible you didn't look at the right place yet.
- People didn't ask that question before or rarely ask and nobody really remember where the answer is.

That said I found in the pulseaudio FAQ some things I didn't try yet, I have the same problem and didn't yet cared to look into it.

Starting musicscore with padsp may do the trick.

No - you don't. It's helpful, certainly not necessary. Because of ALSA
and hardware mixing and the mess that I'm sure Dan would be able to
opine forever about, in many cases only one application can use the
soundcard at once. In desktop Ubuntu, this is often PulseAudio, or
JACK, or MuseScore: clearly these three things compete.

Because Pulse is started first, the wrapper scripts for JACK and
MuseScore check to see if it is running, and then disable it: this is
why programs like Rhythmbox appear to stop working. If MuseScore
notices JACK is running, it uses that.

A further complication arises because MuseScore, naturally, tries to
open the "default" card. In some situations in Ubuntu, this can be a
virtual pointer to the PulseAudio software. If Pulse is suspended
(because MuseScore's start-up has noticed it running), then the
default device won't open and MuseScore will assume there is no sound
output support, and disable synthesis. (This line in output is
symptomatic of this problem: "Alsa_driver: the interface doesn't
support mmap-based access").

Of course, if you have an ALSA-registered hardware/software synth (eg
emu10k1, fluidsynth, timidity, etc), MuseScore can also use ALSA MIDI
commands for output.

JACK is helpful, but is often a pain to set up and use. As a result, I
do not recommend it for most users, especially casual MuseScore users,
who likely are not in need of its advanced features or
configurability. ALSA MIDI is another option, but the UI for that is
non-intuitive, and there are few common hardware synthesizers.

In the last case, MuseScore also supports using the PortAudio library
for output. As you can see when using Audacity, that does not directly
support PulseAudio. I'm slowly writing a back-end for this case[1],
but my time has many pressures on it, and so "slowly" means
less-than-Debian-paced.

I hope this has been helpful.

Starting point:

Setting up Muse Score

Follow these steps to set up Muse Score:

1. Open Muse Score, which is under Multimedia in the main menu (in Gnome: Sound & Video)
2. Open the Edit menu and select Preferences
3. Under the I/O tab:
(a) Ensure that Use internal synthesizer is checked
(b) Ensure that your Sound Font is “/usr/share/sounds/sf2/FluidR3_GM.sf2”
(c) Ensure that ALSA Audio is checked, and at Device, enter “hw:0” (hw:Zero)
4. Click Apply, and then click OK
5. Close Muse Score, and then open it again to start writing your music.

I'm installing musescore again, I let you know if I suceed

[Eggbertx]

I feel stupid now. all i had to do was enable port audio. no APIs or devices were in the lists so i thought it wouldn't work but it did

[BugRocks1]

Just go to Edit -> Preferrences -> I/O and tick the portaudio thingy LoL

OMG! I spend a week, last time looking for an answer and after reading the ubuntu forum I got the comment about portaudio and it works

[BugRocks1]

Oh! you got it too, that is good LoL[COLOR="Silver"]

Hi I'm trying to get playback of Musescore running on Fedora 11. I've set the I/O tab settings as at http://www.micmusic.co.za/forums/mus..._in_linux.html. I don't have Portaudio checked in addition to Alsa as discussed above since I don't know what to put in the Api and Device fields. I was getting the "mmap-based" etc. warning before but I don't anymore. I just don't get any sound on playback. timidity works though. If it's relevant I don't have fluidsynth configured right (yet). It complains about jack not being set up right.

Thanks for any help!

Cheers,

Mike

Sorry forgot to say. If I do check Portaudio in addition to Alsa it uses 100% of the CPU

Cheers,

Thanks. It looks like this answer about portaudio is still needed for Fedora 14. I was about to delete it, but now I can play with it. This will help greatly as I will need to practice some music for Chapel Choir and I can now key it in and listen to my part. Since I don't have a piano at home (and wouldn't know how to play it if I did), this is a good alternative.

This is still an 'issue' with Fedora 15. Thanks to mikeyoleeno and BugRocks1. This was driving me crazy. I guess serves me right for getting clicky in the options menu. Thanks again!
