The SOF ADSP vhost driver consists of two parts: a sound and a vhost part. This patch implements the vhost part of the driver. It handles QEMU communication with the vhost misc device and virtual queues to any VirtIO RPMsg guests. Signed-off-by: Guennadi Liakhovetski <guennadi.liakhovetski at linux.intel.co...

Hello, For some time now have been trying to connect a Samba-3.0.14a-0.4 server running on SuSE Ent 9 linux server to our Exchange 2003 (running on Server 2003 Std w/ SP1) server which is also the AD server for our domain. I can connect to the shares using the AD as the authentication source, so the basic functionality is there but some command output does not show in the way i expect

Hi, I'm porting speex as a DSP task to run using the DSP gateway project. I have some results, but I still need some improments, because I'm still getting some error messages in the mail box system...

Hi All, Is it correct to say that by design, asterisk wont make use of any cards hardware dsp capabilities ? I don't think that any of the hardware cards currently supported have any dsp capabilities, but I wanted to know if for example, in the future a driver was written for a card that did have dsp capabilities, would asterisk be able to make any use of it ? I am only just starting...

Hi, i'm not an expert in dsp but i've seen there is some code to run speex on omap C5X dsp so i was wondering what is the status of this code. Actually my goal is to run a voip application which uses gstreamer on an OMAP 5912 board. As there is already a speex codec for gstreamer, i was wondering if this plugin can already...

...it could work somehow if we're using quality-based VBR- encoding? If you have silence only very few bandwidth is needed. But I really personally dislike all these VBR-things ... so thats why I would never try implementing it :-) If you want to try to do it this way you might have to write a dsp- plugin that loads Oddcast DSP "behind" itself and passes audio through. This way you could mute the audio. Just my 2 cents Stefan On 23 Jun 2003 at 22:37, Bryan Payne wrote: > Yea, > > It's VERY possbile to have the encoder sit idle until a User connects > - we d...

Hi Jean-Marc, I have tested Speex in fixed-point mode on my PC without clicking noise. As I mentioned below, I tested Speex in fixed-point mode running natively on the ARM side of the DaVinci without click noise. I only get the clicking noise when running Speex on the DSP side. For the TI C64+ DSP on the DaVinci processor, the TI-specific switches doesn't do much other than defining the different Speex data types (spx_int16_t, spx_uint16_t, spx_int32_t, etc) and the static heap and scratch size (in config.h and speex_types.h). How do I try "generic fixed...

Hi, I've been trying to get Speex to compile and run on the DSP of TI's new DaVinci System-On-Chip processor, which has both an ARM (ARM926) and a DSP (C64+, based on the C6400). I used the latest code (1.2beta) and followed the example in the speex- 1.2beta1/ti/speex_C64_test trunk to build the Speex library for the DSP. Basically I have a loopback appli...

...eryone, but I figured it out; it's working now. The problem was in my monoToStereo and stereoToMono functions (the Linux OSS driver on the ARM side only supports stereo so I had to convert it to mono before feeding it to Speex); also I had an alignment issue with my buffers I was using on the DSP side.

Hi, I'm running the latest CVS HEAD version of asterisk, and I'm experiencing hangups during voice conversation. This happens quite regularely and often. The problem is in dsp.c, line 1235, where it says accum /= len; But `len', at this point, is 0, resulting in a SIGFPE. The routine ast_frame *i4l_read() in channels/chan_modem_i4l.c:411 is setting p->fr.datalen to p->obuflen which is zero. Has anybody noticed this, too? Since I don't know th...

Jamey, There is a previous posting in the speex archives with a link to the dsp c5x patch.
