Clearly a problem with Alsa. Alsa reports "Most likely this is a bug in the ALSA driver 'snd_usb_audio'." Alsa used to work great. howevere recently it takes 1/2-1hour for pulseaudio to convince alsa to make the 1818VSL available. Jack is not involved at all. Pulseaudio connects straight to alsa. Pulseaudio is my saving grace roight now as it perpetually tries to initialize and get alsa to present the audio interface, which it eventually after an hour does "waking up" Also sorts of decides to "wake up" and then suddenly the 1818vsl is found. How do I "wake up" alsa so that I can use soundcards. I cannot wait an hour after reboot or logout to get alsa to work again. See below What happens after starting pulseaudio is that it cycles the 1818 for about 1/2 hour to get a link to the 181vsl soundcard. That is the first paragraph (1) below which is perpetually cycled by pulseaudio. Eventually it succeeds which gives the BUG comment as below in paragraph (2) ------------------------------------------------------- 1) E: [pulseaudio] udev-util.c: Failed to get card object. E: [pulseaudio] module-alsa-card.c: Failed to find a working profile. E: [pulseaudio] module.c: Failed to load module "module-alsa-card" (argument: "device_id="3" name="usb-PreSonus_AudioBox_1818_VSL_2209-00" card_name="alsa_card.usb-PreSonus_Audio.Box_1818_VSL_2209-00" namereg_fail=false tsched=yes fixed_latency_range=no ignore_dB=no deferred_volume=yes use_ucm=yes card_properties="module-udev-detect.discovered=1""): initialization failed. (**Note this message is cycled for an hour**) 2) (**Then miraculously....Alsa wakes up and pulseaudio can connect to 1818vsl **) E: [alsa-sink-USB Audio] alsa-sink.c: ALSA woke us up to write new data to the device, but there was actually nothing to write. E: [alsa-sink-USB Audio] alsa-sink.c: Most likely this is a bug in the ALSA driver 'snd_usb_audio'. Please report this issue to the ALSA developers. E: [alsa-sink-USB Audio] alsa-sink.c: We were woken up with POLLOUT set -- however a subsequent snd_pcm_avail() returned 0 or another value < min_avail. ------------------------------------------------------ Dont know what happened top Also to behave this way.

[alsa-devel] [PATCH] drm: dw-hdmi-i2s: enable audio clock in audio_startup
by Cheng-Yi Chiang 01 Sep '19

01 Sep '19

In the designware databook, the sequence of enabling audio clock and setting format is not clearly specified. Currently, audio clock is enabled in the end of hw_param ops after setting format. On some monitors, there is a possibility that audio does not come out. Fix this by enabling audio clock in audio_startup ops before hw_param ops setting format.

[alsa-devel] [PATCH] alsa-lib: Remove usleep usage
by Rosen Penev 01 Sep '19

01 Sep '19

usleep was deprecated by POSIX 2008 and is unavailable without deprecated APIs enabled in uClibc-ng.
