Flakey audio that works one boot, not the next ? Have to restart media services all the time

1

Since setting up my Acer AX1300 AMD Phenom based HaikuBox, I keep loosing my media preferences.

Let me explain…

I am having to use OpenSound since Haiku R1A4 did not see the NVidia audion system.

Since the install of OpenSound, I do get audion, but I lose it often between boots.

I can boot the system, try audio, it works. Upon next boot, no audio, I check Media Prefs and the NVidia HD Audio input and output are no longer being seen in audio settings.

I restart media services, reboot system, and 50/50 I get audio again. Doing this several times it finally remembers the NVidia HD Audio and I am able to play audio.

So, without doing any changes between reboots, audio comes and goes and I have to restart media services multiple times until I hear my speakers come alive.

Odd.

Anyone have this issue?

I’ve seen this on BeOS and Haiku with some sound cards. It may be a driver bug, some things that come to mind:

  1. Try different settings like different sampling rates in the media preferences. It probably won’t help but it’s easy to try.

  2. Try restarting the media kit with all but one of the processors turned off. This might work around race condition type bugs?

  3. Remove some of the RAM, if the total of system RAM + video RAM is < 4GB, then all sound buffers will be allocated below the 4GB threshold. Useful if the soundcard driver has a memory allocation bug (the Delta 1010 driver had/has this issue if I recall, others should be regarded as suspect)

Also is there any pattern or is it totally random? Does it behave differently between a coldboot and a warmboot? Any difference between rebooting and just restarting the media kit?

So far the pattern is not detected by me.

I just did a warm reboot, all is fine.

Powered down and reboot, same working fine now.

I will try leaving the PC off for a while and come back and see what happens. My thought, the longer I leave it off, the more chance she does not boot with sound.

Thanks for the other advice.

Could there be a conflict between a hardware driver and opensound?

What sound hardware do you have? Is there a Haiku driver that matchs it?

What happens if you remove that driver and leave only opensound?

Or remove opensound and leave only the driver.

Try both ways.

Check if HDA driver is loaded using

listimage | grep hda

If it’s loaded then move it out of your /system/add-ons/… folder.
