Re: [SlimDevices: Touch] Instructions for connecting USB DAC to Touch
Hi everyone, Joel, i had the same problems with clicks and pops particularly on big files (.m4a, .wav files, not so much on mp3, nor radios, nor spotify), with Wifi, or ethernet. I changed some parameters in the kernel, and change buffer values based on http://soundcheck-audio.blogspot.com/ recommendations : its really better, noticeably less clicks This is what I do : create a new file that will be start on boot : vi /etc/init.d/rcS.local put these lines : echo 2048 /sys/class/rtc/rtc0/max_user_freq echo 10 /proc/sys/kernel/sched_min_granularity_ns echo 10 /proc/sys/kernel/sched_latency_ns echo 50 /proc/sys/kernel/sched_wakeup_granularity_ns echo 10 /proc/sys/kernel/sched_rt_period_us echo -1 /proc/sys/kernel/sched_rt_runtime_us echo 1 /proc/sys/kernel/sched_compat_yield then add the x right : chmod a+x /etc/init.d/rcS.local Edit the files /etc/squeezeplay/userpath/settings/SqueezeboxFab4.lua and /usr/share/jive/applets/SqueezeboxFab4/SqueezeboxFab4Meta.lua. I changed alsaPlaybackBufferTime et alsaEffectsBufferTime to 50 instead of 2. This value might be extreme, I really don't know. You can raise the default value step by step if you prefer. Remember to backup these files before. And keep in mind that those files will be overwritten on each firmware upgrade. Then reboot the Touch. -- cocamegadose cocamegadose's Profile: http://forums.slimdevices.com/member.php?userid=40903 View this thread: http://forums.slimdevices.com/showthread.php?t=82110 ___ Touch mailing list Touch@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/touch
Re: [SlimDevices: Touch] Instructions for connecting USB DAC to Touch
Hi there,
Just a post to confirm that this mod works with (my) HRT Music Streamer
II+.
BUT (in my case) it did not work just out of the box (my
Squeezebox is brand new, just bought today).
The HRT was not listed in aplay -l. I tried to reboot a hundred times,
to hotplug/unplug ... still nothing in aplay -l.
But when I tried to plug an USB drive for the first time, then reboot
with the reset button with the HRT plugged in, it worked : the HRT was
detected after the reboot and listed in aplay -l (as card 1)
Now it is working perfectly.
So it could help to plug an USB hard drive once before trying John's
mod.
For the record, here is the result of aplay -l :
# aplay -l
List of PLAYBACK Hardware Devices
card 0: TXRX [MXC SPDIF TX/RX], device 0: MXC_SPDIF [MXC_SPDIF]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 1: II [Music Streamer II+], device 0: USB Audio [USB Audio]
Subdevices: 0/1
Subdevice #0: subdevice #0
card 2: fab4 [fab4], device 0: fab4-ak4420 []
Subdevices: 0/1

... and my /etc/asound.conf :
pcm.usbdac {
type hw;
card II;
}
pcm.plugusb {
type plug;
slave.pcm usbdac;
}
ctl.plugusb {
type hw;
card II;
}
pcm.!default plugusb
Thanks John for publishing this mod !
Squeezebox Touch and HRT Music Streamer II+ is a great combo : easy to
use, compact, capable of great sound.
