My problems seem to be centered around audio so far:
1. audio over HDMI - Ok, I can get audio working over HDMI, but not properly - All I get is a 2 channel mixdown, and I feel pretty confident that the problem lies in the HDMI communications between the XA2 and the next component downstream. In my case that component is the Crystalio 2 video processor, and since it is not an audio processing device, my feeling is that it is not reporting the needed "audio EDID" (if there is such a thing) properly back to the XA2.
From the XA2 manual:
Select this when an HDMI device is equipped with buit-in Dolby Digital, DTS, MPEG, or linear PCM decoder is connected to this player.
Well, guess what? The C2 is not such a device, as its purpose is simply to pass the audio stream on to the next device. As a result, the only audio that passes is 2 channel PCM which sounds to me like it is downmixed. The manual continues:
Digital audio signal (bitstream audio) is output. If a connected HDMI device does not support bitstream audio input, sound is converted to linear PCM format.
Yup, that sounds about right. Toshiba needs to change its firmware to allow for a "manual" selection of supported formats that will be passed via HDMI regardless of whether or not the attached device supports them, as my example will be typical of people who use video processors. As things stand now, I am limited to a downmixed 2 channel PCM track over HDMI, so I am not getting the full benefit of HDMI's audio capabilities.
2. 5.1 analog passthrough - This is more of a request than a bug/problem. There are those of us who would simply like to pass the full bandwidth signal directly from the decoder to the audio processor via 5.1 channel analog connects. It would be handy to have a button that could be used for a simple bypass of any and all bass management and time alignment performed in the player so that as clean a signal as possible would be delivered to the pre/pro or receiver where the processing would in all likelihood be significantly better.
3. The LFE bug - I really haven't figured out what is happening here so far, but when I run the test tones in the 5.1 setup menu, I can here the test noise just fine for the 5 speakers, but I am getting no subwoofer output at all, regardless of how high I set its level. When I actually play a movie, the LFE is certainly present in all of its glory, but not hearing it at all during the testing concerns me. I am sure it will be of great concern for those who are actually performing their bass management in the player...
