Getting AdvMenu background sound working
  • nayphee
    I'm trying to get AdvanceMenu background sound working. I filled a directory with MP3 files (got one of "PacMan fever" !)
    but when the music starts playing it sounds grating and terrible.

    I seem to get the impression that the Pi is getting floored by resources placed on it by the menu, and that the sound is under the pump or something. I see some old threads relating to turning off the alsa device, but even when I turn the setting back to default it still sounds terrible.

    Perhaps it's the sample rate of the MP3 it doesn't like? I will experiment. My Pi is clocked to 900Mhz

    Hey nayphee,

    I've tried to get the sound in advmenu to work properly and it's just awful...Someone else had commented on the board that it's no better via a USB audio device, so I'm assuming it has more to do with the limitations of the Pi than it does with advmenu.
  • nayphee
    I tried reducing the sample rate in advmenu, but this didn't help either.
    I guess I can keep playing with twiddles, or maybe reconvert the music to a WAV, or maybe drop the MP3 to a lower bit rate.

    Additionally, I thought it could be the volume. It seems like it's exceeding the speaker cut off frequency and hitting the red levels. tried changing the volume to -7 and this didn't help either. :(

    I also tried converting my files to .wavs as well as changing the sample rate, bit rate, and volumes...no luck. Sorry I don't have a better answer :(

    I noticed this:-

    Although the audio I'm hearing sounds more grating... as if it's being sampled by a Commodore 64 tape deck :D

    I'm using pimame 0.7 beta 1, but perhaps I might have a go at using the pimame installer on the latest raspbian. Maybe there is a firmware fix. Additionally I do notice some sound bcm errors in the console when I leave advmenu, so sound is probably having issues somewhere.

    I really want this to play in the background!!
  • casiokid
    Ha! That's awesome!

    I hope you find a solution. I ended up giving up and using mame4all instead...much smoother game play, configurable splash screen and menu, but nowhere near as configurable as AdvMenu.

    Good Luck!

    I've noticed that mame4all works a lot better. I couldn't get Asteroids Deluxe to display in Advancemame, but it worked OK in Mame4all. I think there are a few other games I couldn't get working in Advancemenu that are OK in Mame4all.

    Fewer display/sound dropouts in Mame4all as well, but I have no idea what the hell is causing this problem. It could just be that my TV is giving the Pi a hard time. That's not very promising if I want the pi to run on any HDMI enabled TV I throw at it.
  • casiokid
    I'm POSITIVE it's a limitation of the Pi and how AdvMenu works...I tried it out of the analog output and got the same results.
  • nayphee
    That sucks.

    I'm almost tempted to try compiling advancemame on FreeBSD/pi just for fun to see if it's any better! (doubting it, but could be a fun experiment)
  • casiokid
    Definitely a fun experiment, but not an ideal work around! If you do get it working though, please let us know!

    I would love to see how it runs in FreeBSD :D
  • nayphee
    I'm not even sure if they have HDMI working on the FreeBSD build. I tried it the other day only to get a blank TV screen. I believe it may work only via console.
