Stuttering text-to-speech since MMAP update to bcm2835 driver

[cromarty]

Since about a month ago, when the MMAP change was made to the sound driver, text-to-speech with espeak is now almost unusable. Speech is very broken and slows down when speaking long strings, including dmesg

Have deleted /etc/asound.conf. No help

10 second sound delay, plays for about 10 seconds and then begins to drag out audio

I have now discovered that using pulseaudio with espeak instead of
portaudio solves this

It seems to have returned. I noticed a similar issue with recent firmwares.

I gave this solution (http://www.scribd.com/doc/232827505/Audio-Errors-With-Espeak-Raspberry-Pi-Stack-Exchange) a try, changing the front speaker assignment but it didn't help (of course I reloaded the settings with sudo /usr/sbin/alsa force-reload).

@cromarty according to your last statement (17 Jan 2014) this issue appears to have been fixed. Please close this issue if that is the case.

[cromarty]

No it hasn't been fixed. Still happening.

I did work for some time, then it got worse and sometimes it's just one continuous buzzing sound.

I believe the sound system (Linux side) has changed since the last comment. Does this still happen?

I recently confirmed that the stuttering no longer happens. I am assuming also then that the kernel oops caused by null pointers being passed to the kernel by the vchiq has also stopped. Mike
