Touch has no fixed volume setting

[JJZolx]

Unlike Squeezeboxes before it, there is no ability to set the output volume to be fixed at 100% on the Touch. Please vote for bug 14807.

Agreed & voted. Touch also should have a way to turn of the IR remote sensor as well, like the SB3.

How does that go then for bit-perfect output from the Coax SPDIF?
Will the digital volume still be "in circuit" and therefore teh output into my Dac NOT be bit-perfect?

I presume when you set the volume to 100% it will be bit-perfect. There just doesn't seem to be a means to lock it at that level, so you have to pay attention that you don't accidentally change it.

See this discussion of VolumeLock and Squeezebox Radio -- the same is pretty much true of VolumeLock and SB Touch. It cannot prevent you from changing the volume via Touch's screen or IR remote, but it can quickly restore the volume. That's not a good substitute for addressing Jim's ticket though -- I just offer this as a short-term hack until someone makes a proper fix.

Touch offers a really cool new possibility on the fixed output front. With 100% fixed (when available) and a $10 USB-to-serial cable (and a not-yet-written applet), Touch should be able to directly control volume and more on amps & receivers that have RS232 inputs -- and to effectively web-enable amps & receivers with RS232 ports.

Jim, thanks for posting about this. Votes should help, as Logitech recently downgraded the importance of this request (see its change log), pushing it farther into the future. Since the software involved is all BSD-licensed, anybody could create a patch (and even publish it directly to other customers thanks to Erland's Patch Installer applet), so I hope this problem will have a good resolution pretty soon.

Voted. Can someone confirm the Touch has a preamp volume control and that it works OK? For the SB3 the "optimal" setting for using digitals out was to set the output level to 100% and the preamp volume attenuation to max 63 for the analog outs...

I don't think it does have a preamp volume control.

[jstraw]

Call me nuts but I think line outs should always be at a fixed line level. I can understand an OPTION to make them adjustable for powered speakers but not as a default.

so is there a question then about whether the output from SPDIF co-ax is bit perfect then?

Sorry to be "projecting my doubts", but it WAS a significant thing with the SB3, in that switching the digital volume and analogue outputs "off" was basically the only way to achieve the best "bit-perfect" output through the co-ax SPDIF.

i ask just becasue I'm using the Touch purely as a digital transport into a Dac.

Same here,(or at least will be once my Touch is delivered)so very interested in an official response to the question regarding a bit perfect output.

The digital out IS bit perfect as long as the volume is set to 100, its been tested by several people and does correctly pass a DTS file. Just don't change the volume and you'll be fine.

+1 - categorically bit-perfect when vol=100 (DTS and HDCD prove this).
The Touch doesn't need the -63dB setting for the analogue outs that was useful on the SB3).

There is no additional "analogue" level control on the Touch.

The Touch is a new circuit not a tweak to the SB2/3 circuit.
On ALL SB's the digital level control is always "in-circuit".

The analogue outputs on the SB3 did NOT need to be off for bit-perfect output - the digital level needs to be at 100 and no replaygain...

As I don't need client-side HDCD decoding or dts playback, I prefer to use replaygain and proper gain staging through my system. I'm never going to agonise about the perfection of the 16th or 20-24th bits :-)

I do agree that an option to lock the Volume at 100 should be provided (although replaygain will still override that!). I've voted.

Many thanks for the info...
