1212078 - No sound from a freshly flashed Flame

Status: RESOLVED INVALID

(Firefox OS Graveyard :: General, defect)

Description

[Ola B]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:41.0) Gecko/20100101 Firefox/41.0
Build ID: 20151001044230

Steps to reproduce:

Built, compiled, and flashed Firefox OS v2.5 to a Flame device (master branch).

The latest commit in my B2G git history is from 22nd Sep. git pull tells me "Already up-to-date."

When building I use the following options (in .userconfig):

PRODUCTION=1
VARIANT=userdebug
export NOFTU=1
export B2G_DEBUG=0

I also build with external Gecko, namely mozilla-central rev 265900.

Tried to flash two different Flame devices, both are unable to play sounds from any app. Everything else works fine, such as voice playback and vibration.



Actual results:

No sound from any app, including Music player, ringtone preview, tap sounds, etc.

There have been similar issues before, such as:
https://bugzilla.mozilla.org/show_bug.cgi?id=1091788
https://bugzilla.mozilla.org/show_bug.cgi?id=1091659

But I do not see any clear explanations or solutions.


Expected results:

Sound waves are expected.

Can QA reproduce?

Comment 2

[John Thomas [:Johnt]]

I was unable to reproduce this issue using the Flame 2.5. Sounds are being played successfully. I attempted to Full flash (After rebasing) as well as shallow flashing. Reporter, which build were you using?

In the mean time I am leaving Qawanted tag on for others to attempt to find a proper STR if it does still exist on current builds.

Reporter, could you go into Settings > Sound, and check whether you have correct settings for different types of sounds?

Comment 4

[Ola B]

Yes, I have checked the sound settings, and they looks fine.

This is the output from the check_versions.py script (is that what you need?):

It's odd that you are showing no gecko revision.  We don't have access to the build you made but were unable to reproduce on builds made by buildbot around the same time yours was created.  Does this also occur if you are using any other builds?

Comment 6

[Ola B]

I'm making a new build now. It will take some time, so I'll get back once it's done.


Just to be transparent about what I do:

In mozilla-central:
> hg pull -u
> rm -rf objdir-gecko
(I just realized I havn't removed this folder previously, perhaps that's the problem?)

In B2G:
> git pull
> ./repo sync
> rm -rf out
> ./build.sh
> ./flash.sh

Everything should be vanilla, except .userconfig:

PRODUCTION=1
VARIANT=userdebug

export NOFTU=1

# Gecko settings
export B2G_DIR=${B2G_DIR:-$(cd $(dirname $0); pwd)}
echo "B2G_DIR = ${B2G_DIR}"

export GECKO_PATH=${B2G_DIR}/mozilla-central
echo "GECKO_PATH = ${GECKO_PATH}"

export B2G_DEBUG=0
echo "B2G_DEBUG = ${B2G_DEBUG}"

export GECKO_OBJDIR=${GECKO_PATH}/objdir-gecko
if [[ "${B2G_DEBUG}" != "0" ]]; then
  export GECKO_OBJDIR=${GECKO_OBJDIR}-debug
fi
if [[ "${GECKO_PATH/*mozilla-inbound*/mozilla-inbound}" == "mozilla-inbound" ]]; then
  export GECKO_OBJDIR=${GECKO_OBJDIR}-m-i
fi
echo "GECKO_OBJDIR = ${GECKO_OBJDIR}"

# Gaia settings
export GAIA_PATH=${GAIA_PATH:-$(cd gaia; pwd)}
export CUSTOM_SETTINGS="${GAIA_PATH}/build/config/custom-settings.json"
cat > "${CUSTOM_SETTINGS}.new" <<EOF
{"devtools.debugger.remote-enabled": true}
EOF
if [[ -f ${CUSTOM_SETTINGS} ]] && cmp "${CUSTOM_SETTINGS}" "${CUSTOM_SETTINGS}.new" >& /dev/null; then
  rm "${CUSTOM_SETTINGS}.new"
else
  mv "${CUSTOM_SETTINGS}.new" "${CUSTOM_SETTINGS}"
fi

Now I have flashed the phone again with a newly built system. The problem is still there.

I did exactly as in post 6, except for 'hg pull -u' since I realized I had to do:
> ./mach  mercurial-setup


The output from check_versions.py:

Build ID               20151008072501

Can it be related to firmware? 
Is there any more information I can give?

Comment 8

[Pi Wei Cheng [:piwei] (inactive)]

NI Naoki since we're unsure whether reporter's flashing the device correctly.

Comment 9

[Ola B]

I think I have found the source of the problem now. I decided to redo everything from scratch.

Everything worked fine until the backup state early in the build state. Somewhere during that process I got the following:

c/security/cacerts/6adf0799.0
pull: /system/etc/security/cacerts/69105f4f.0 -> ../../../backup-flame/system/etc/security/cacerts/69105f4f.0
pull: /system/etc/security/cacerts/67495436.0 -> ../../../backup-flame/system/etc/security/cacerts/67495436.0
Pulling files from ../../../backup-flame
cat: ../../../backup-flame/system/build.prop: No such file or directory
Pulling "libalsa-intf.so"
cp: cannot stat ‘../../../backup-flame/system/lib/libalsa-intf.so’: No such file or directory
Failed to pull libalsa-intf.so. Giving up.

 > Build failed! <

I would think that this mean that somehow this file was lost when this was done previously. Therefore it was also missing in every build I made from my previous build tree. I haven't had time to fix this and test a new build yet, but the problem seems obvious.

In the future, as a lesson from this case, perhaps one could consider to include an extra check in the build script to make sure all (important) external system files are there?

[Naoki Hirata :nhirata (please use needinfo instead of cc)]

Actually the problem is that your pull is old.
You need to resync your branch.
https://github.com/mozilla-b2g/device-flame/tree/kitkat-v2 doesn't use that lib file.

Please use:
./config.sh flame-kk
./repo sync --force-sync

or reclone the B2G directory again from scratch and the ./config flame-kk

Thanks Naoki.
