Gemini PDA - Sailfish OS / Pulseaudio wierdness

« on: April 27, 2019, 11:40:01 am »

Having updated to SF 3.0.3.8, I though I would see if anything had changed with the Pulse Audio speaker/headphone situation:

Speakers continue to operate when headphones are plugged in, and headphone are mono.

Unfortunately, no change with 3.0.3.8.  However, I can still use shell commands to force the pulse audio system to switch:

pactl set-sink-port 0 output-wired_headphone
pactl set-sink-port 0 output-wired_headset
pactl set-sink-port 0 output-speaker

Note that headphones and headset both seem to route to only the headphone jack, resorting stereo operation.  And I found a nice GUI program on open-repos simply called "audio output" which lets me change the audio output from the touch interface.  So things are looking good.

All going well until I discover that using the Media application, every time a song finishes playing and a new one starts through the headphones, the volume drops by about 10 dB. If I switch pulse audio audio sink between  output-wired_headphone and  output-wired_headset, levels are restored.  But I need to toggle after every song. Pulse Audio isn't showing any volume change.  So I assume it's some hardware adaptation problem with a hardware course gain setting being reset in the audio codec IC.

Is anyone else seeing this?  And idea what it might be?

Gemini PDA - Sailfish OS / connman wifi tether

« on: November 07, 2018, 08:36:27 pm »

I have heard that others have been able to get wifi tethering to work on the Gemini community edition (PC flash image) of sailfish via the terminal/shell. I have been trying to use "connmanctl tether wifi on <ap-name> <ap-password>" under the su-devel root-ish account.  But no luck.  I always get back:

Error enabling wifi tethering: In Progresses

After which the GUI continues to show WiFi operating as a client.

Yes I have 4G data service.  But I noticed that "connmanctl scan wifi" yields no results.  Is connman broken in the community edition?  If so, how is networking handled by the GUI in the first place?  Maybe there is a "special" version of connmanctl tucked away some place?

I am about to do some traveling and will be needing to do a WiFi tether from time to time. So any help would be appreciated.

Thanks!

Gemini PDA - Sailfish OS / USB Ethernet adapter use

« on: September 01, 2018, 11:55:53 am »

I am trying to use a USB Ethernet adapter on my Gemini.  I installed the usbutils package to get access to the lsusb command.  This shows the ethernet USB device when plugged into the Gemini's left USB port.  However, the interface doesn't show up in the ifconfig -a command result. I have no idea how sailfish detects and changes the network interface list.  Since sailfish has no /etc/network directory, I assume networking setup involves the systemd beast.   Has any one been able to get a USB Ethernet adapter to working?

Gemini PDA - Sailfish OS / default route missing

« on: July 27, 2018, 01:24:22 pm »

As I continue on my Sailfish/Gemini journey, I finally got LTE data working in the USA on the Verizon network.
With that now working, I discovered a new Sailfish bug:  When the device switched the network default route between LTE to WiFi, the default route disappears from the routing table,
as observed via shell executed netstat -r.  I need to reboot to get the network stack working again, or manually add a default route back in as su-devel:

route add default gw 192.168.11.1 wlan0

for example to get things working again with my inhouse WiFi.

Also, I can receive phone calls while registered on LTE, but after the call, Sailfish compains that no SIM is inserted until I reboot.

 I am still learning my way around this OS, so I don't think I can be much help yet.

Gemini PDA - Sailfish OS / Mono headphone output?

« on: July 23, 2018, 12:06:27 pm »

I have come across two audio related problems with Sailfish CE on the Gemini.  First, when headphones are plugged in to the device, the speakers continue to produce audio along with the headphone.  It is my understanding that the Gemini has a single stereo audio DAC, but I expected the OS/driver to switch the output path from the speakers/amplifier to the headphones, when the headphones are inserted.  In addition, the headphone are mono, along with the speakers..  That is certainly not right.  I know the speakers are mono (and apparently phase inverted), but my understanding was that this hardware bug did not apply to the headphone jack.  Has any one else noticed this behavior?

Bluetooth audio sending works fine.
