# Note 1: use the eev command (defined in eev.el) and the
# ee alias (in my .zshrc) to execute parts of this file.
# Executing this file as a whole makes no sense.
# An introduction to eev can be found here:

# http://angg.twu.net/eev-intros/find-eev-quick-intro.html
#
# Note 2: be VERY careful and make sure you understand what
# you're doing.
#
# Note 3: If you use a shell other than zsh things like |&
# and the for loops may not work.
#
# Note 4: I always run as root.

# Note 5: some parts are too old and don't work anymore. Some
# never worked.
#
# Note 6: the definitions for the find-xxxfile commands are on my

#pulseaudio
<edrx> hello - I am a newbie to pulseaudio - and btw I'm mostly a
CLI/Emacs person, and my knowledge (and use) of the sound
devices is quite basic... and I have a newbie question, here
it goes: I just got an external phone amplifier that was
supposed to be automatically recognized as an external USB
soundcard... lsusb lists it as "Bus 002 Device 003: ID
08bb:2900 Texas Instruments Japan PCM2900 Audio Codec", but
alsaconf do
<edrx> esn't list it as an option... any hints? also, is there a
way to make pulseaudio ask alsa to use a specific soundcard?
(I also have an on-board intel 82801G soundcard)...
<edrx> I'm learning to use the "pulseaudio -C" CLI, but it seems
(?) to expect device names given as "/dev/..." for choosing
sound sinks...
<edrx> so my question may be an alsa question 8-\

Hi list,
I have two Debian 10 partitions on my laptop - a venerable ThinkPad
T400 with libreboot - and in one of these partitions (in /dev/sda5,
a.k.a. the "bad partition") sound doesn't work, and in the other one
(/dev/sda4, a.k.a. the "good partition" from here on) it does...
The "bad partition" had Debian 9, and after I upgraded it to 10 with
"apt-get dist-upgrade" sound stopped working on it (details soon). I
then installed Debian 10 from a installation pen drive on an empty
partition to be able to test things on both; sound works on it
perfectly, so let's call it the "good partition".
I've tried several sound debugging recipes that I found on the
internets and they didn't work, so I've decided to use this as an
excuse to learn more about sound on Linux.
"Sound doesn't work" here means that all applications that play
sound - including speaker-test, that seems to be very low-level -
behave normally, but I can't hear anything - even when I use alsamixer
to set "Master", "Headphon", "Speaker", "PCM", "Beep" and "Internal"
all to the maximum level.
I tried to follow the instructions here,
https://wiki.debian.org/Sound
and I sort of converted them - except for the step with pavucontrol;
more on it at the end of the e-mail - into a script... this one:
logthis () { echo $*:; eval $* 2>&1; echo; echo; }
{
# Debian version
logthis cat /etc/issue
logthis cat /etc/debian_version
logthis cat /etc/os-release
logthis lsb_release -da
logthis hostnamectl
# List devices and PCMs
logthis aplay -l
logthis aplay -L
# Drivers and modules
logthis "lspci -vvv | grep -A8 Audio"
logthis "lspci -knn | grep -A2 Audio"
# Permissions
logthis groups
logthis ls -lAF /proc/asound/
# This partition
logthis "mount | grep 'on / '"
# ALSA state
logthis "rm -f /tmp/o; /usr/sbin/alsactl -f /tmp/o store; cat /tmp/o"
} | tee ~/oalsa
I ran it in both partitions and compared the outputs with tkdiff.
Here are the relevant differences:
1) In the bad partition the output of "aplay -l" is:
**** List of PLAYBACK Hardware Devices ****
card 0: Intel [HDA Intel], device 0: CX20561 Analog [CX20561 Analog]
Subdevices: 0/1
Subdevice #0: subdevice #0
card 0: Intel [HDA Intel], device 1: CX20561 Digital [CX20561 Digital]
Subdevices: 1/1
Subdevice #0: subdevice #0
and in the good partition it is:
**** List of PLAYBACK Hardware Devices ****
card 0: Intel [HDA Intel], device 0: CX20561 Analog [CX20561 Analog]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 0: Intel [HDA Intel], device 1: CX20561 Digital [CX20561 Digital]
Subdevices: 1/1
Subdevice #0: subdevice #0
Note the "Subdevices: 0/1" in the bad partition.
2) In the output of "/usr/sbin/alsactl -f /tmp/o store" some of
fields "value.0", "value.1", "dbvalue.0", "dbvalue.1", are
different between the two partitions, but they are all in the
allowed ranges and they look reasonable to me (i.e., to my
untrained eye).
3) In the output of "/usr/sbin/alsactl -f /tmp/o store" the
subsections of "state.Intel { ... }" appear in a different order.
In the good partition the subsections 10-25 are numbered like
this,
control.10 : name 'Beep Playback Volume'
control.11 : name 'Beep Playback Switch'
control.12 : name 'IEC958 Playback Con Mask'
control.13 : name 'IEC958 Playback Pro Mask'
control.14 : name 'IEC958 Playback Default'
control.15 : name 'IEC958 Playback Switch'
control.16 : name 'IEC958 Default PCM Playback Switch'
control.17 : name 'Master Playback Volume'
control.18 : name 'Master Playback Switch'
control.19 : name 'Mic Jack'
control.20 : name 'Internal Mic Phantom Jack'
control.21 : name 'Dock Mic Jack'
control.22 : name 'Speaker Phantom Jack'
control.23 : name 'Dock Headphone Jack'
control.24 : name 'Headphone Jack'
control.25 : name 'SPDIF Phantom Jack'
and in the bad partition like this:
control.10 : name 'IEC958 Playback Con Mask'
control.11 : name 'IEC958 Playback Pro Mask'
control.12 : name 'IEC958 Playback Default'
control.13 : name 'IEC958 Playback Switch'
control.14 : name 'IEC958 Default PCM Playback Switch'
control.15 : name 'Master Playback Volume'
control.16 : name 'Master Playback Switch'
control.17 : name 'Mic Jack'
control.18 : name 'Internal Mic Phantom Jack'
control.19 : name 'Dock Mic Jack'
control.20 : name 'Speaker Phantom Jack'
control.21 : name 'Dock Headphone Jack'
control.22 : name 'Headphone Jack'
control.23 : name 'SPDIF Phantom Jack'
control.24 : name 'Beep Playback Volume'
control.25 : name 'Beep Playback Switch'
About pavucontrol: in the bad partition the only output device that
appears in the "Output Devices" tab is called "Dummy Output". This
looks like a red flag, but I got the impression - please confirm -
that PulseAudio runs on a level above ALSA, and problems with
PulseAudio should not affect the behavior of speaker-test.
So: any hints? What should I add to my script to compare the behavior
of ALSA in the two partitions? Am I wrong in thinking that
speaker-test ignores PulseAudio? How do I examine the status of
PulseAudio without using the GUI? Are there ways to mute and unmute
the sound using the functions in /usr/share/alsa/utils.sh? What
else?...
Thanks in advance!
