Fuze and Griffin Dock line out
ardeeon:
with this kind of patches, is it safe to say that we will see Line-Out to be fully supported on fuze v2?

I just want to pass on a big up to tenfoot, you made me a very happy camper. I can now hook my fuze up to my SET amp. The sound from my sansa(s) is really clean, I can forget the usb dac for a while.
It took me a few minutes to find the LO setting:
Settings>General Settings>System>Line Out
And yes there is a little popping when toggling between on/off, so probs best not to do that live.
I made a DIY line out so I can fit both headphones and the LO cable at the same time. I can confirm this patch shunts the headphone volume for those that were curious / concerned about battery life.
Fuze/Clip + Yuin PK3 is still by far the cheapest ticket to audio nirvana, but now I can drive my Grados with my headphone amp using Rockbox in all its gapless glory. This patch seals the deal, time to invest in a new fuze, the battery in mine is about cooked.

Hi. Rockbox newbie here. I just bought a Fuze v2 + Griffin iTrip car adapter, and discovered this problem. tenfoot's lineout patch helps, but not quite enough. I would like Rockbox to automatically detect, on powerup, that it is connected to a car adapter (not a USB host) and that it should 1) boot itself, not the original FW, and 2) enable lineout automatically.
Working with the source and the 1.13 revision of the AS3525 datasheet, I've instrumented debug-as3525.c to print what I thought were some likely candidates: ENRD0-2, some USB_[IO]EP[0-3]_{CTRL,STS}, GPIO[A-D]_IS and _MIS. No joy. ENRD0 flips from 0x00 to 0x28 when plugged in to the Griffin, as expected, but that's indistinguishable from computer USB.
Can anyone suggest other registers to monitor? Other things to try? I am highly motivated to fix this. Thanks in advance.

Booting into the original firmware is actually by design since USB is very unstable in rockbox on your player.you can disable that by editing mkamsboot and flashing a new bootloader. Be careful though a bad flash will brick your player.
Regarding line out, I always thought it was detrctedbby one of the dbop in pins like the buttons and wheel on the first fuze.

Understood. To clarify my earlier post, I don't necessarily want to boot in USB mass storage mode. I want Rockbox to detect the car adapter. I.e. "I sense USB (bit 3). Now: if connected to computer, boot into original FW (current behavior). If connected to car adapter, boot into Rockbox (music mode, not USB mode) and enable line out".

Will check those as soon as I have time. Thanks for the suggestion.
