Sound issues 10.04
Hi Guys, Just got 10.04 running in a virtual machine. I have some sound output issues, which is a big stumbling block. The sound under wine seem to drop out for about one second and then cut back in. I am using this for tts generation so if you can imagine that I am getting This a test of the open-sapi server. Instead of This is a test of the open-sapi server. Always about one seond in it seems to skip the audio output. Any ideas??? wine seems to be outputting the audio to pulse but i have very little experience with narrowing down whats at fault. Do we think it is wine or piulse is anyone else experiencing this issue at all?

Re: Sound issues 10.04
What I'd ask, is how much RAM have you gotten allocated to the virtual machine ? As I read it, you are running 10.04 on a virtual machine, and then asking the 10.04 to run Windows as virtual machine .. To be honest, fair play to the guys who write the stuff - a virtual machine, within a virtual machine. Your drop-outs may be simply due to there being too many processes going on for either your CPU or there is insuficient RAM to run WINE within an already virtual machine. Regards, Phill.

Wine + pulse audio output is a known bug, and one that people from the wine community, and I think pulse are trying to solve, with little success so far. Someone wrote a native pulseaudio output driver for wine, however users who have tested it have reported mixed results. You could consider piping the audio to a file and playing it in the native linux environment, but what would be better is if opensapi could use speech-dispatcher's audio output routines. I am not sure what language opensapi is written in, but if its c, then you just need to link against libspdaudio somehow, however header files for doing so are not provided in the speech-dispatcher packages, only the source. This is something I intend to address. Luke -- Ubuntu-accessibility mailing list Ubuntu-accessibility@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-accessibility
Re: Sound issues 10.04
The possibilities are endless but to give us a bit of a clue I think it is a pulseaudio issue that is fixed by using the experimental packages found in Neils ppa. https://launchpad.net/~neil-aldur I just added the ppa and updated the software from it, I was not paying that much attention but i think that pulse is more than likely the candidate here as wine was not touched in the update, I did check that much at least. I have got enough ram allocated to it about 512 (which is not a lot but just running these apss does not kill the machine off) I think and one of my dual core processors and it copes okay. A little slow. It very weirdly always seems to be the second or third word that is totally skipped. I tested it with 1 2 3 4 5 6 7 8 9 10 9 out of 10 times it skipped the two and 1 in 10 times skipped the three but seems to chop off the beginning of the words around that time with a slight popping sound that is all too familiar with pulse. I am still testing but there is already a solution to the problem lurking in the ppa, will see if I can catch neil. -- Ubuntu-accessibility mailing list Ubuntu-accessibility@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-accessibility
