First, thanks esp. to Scott Bennett, Robroy Gregg, and Polytropon. Indispensable friendliness in sharing their experiences, tips, and = tricks, and suggestions. Forgive me if I ask a bit more of you (and others) as this great = opportunity of tapping your interest and aid just a bit more... These "mix" success stories are useful news!=20 It is also great to hear of 'external' sound system experience. In such a climate, I offer up a strange appearance, through = re-connection luck, of my soundbar suddenly being recognized, although = to what degree I am uncertain. I hate to wait until runtime issues ask for camouflaged resolutions, so = this before-the-problem research will surely help, and if it is not an = imposition. Initially, I discovered the lack of a sound system in my server (vs. = serving out or streaming sound files to a client's sound system) because = a FreeBSD base or port installer option I may have clicked in one of = many DOS-like install checklists, kept giving me bootloader error:s = w/r/t "mixer" and a "missing", unusable, and/or undiscovered sound = device. Did I mention mistakenly appearing to be properly-attached? ;-) Yesterday, I swapped desktop locations of my FreeBSD monitor and my = Macmini5,1 running MacOSX10.7 Lion -- the last [cr]Apple OS to = supply/support X11, a 'security bust'-must required by their cohorts in = the PRISM-NSA association, much as they've now removed NFS, BSD, and = security-rich modules/modalities which guard against intrusion except by = them and their BFFs). After the swap I've noticed lines that may or may = not have been there before w/r/t its "Dell Stereo USB Monitor Soundbar = AC511" attached like a lamprey to the the 'landscape' bottom-side of its = 90-degree-flippable, very code-reading "friendly", Dell 22 Monitor = (model) P2217H. The FreeBSD system wants to use it, or is, but may be = having issues, as a loose "eye" with pre-logged screen-scrolls was = missed or altered by a re-seated connection. Either way: ugen4.2: <Microchip Tech USB274> at usbus4 (disconnected) uhub5: at uhub2, port 6, addr 2 (disconnected) ugen4.3: <Dell AC511 USB Soundbar> at usbus4 (disconnected) uaudio0: at uhub5, port 3, addr 3 (disconnected) pcm0: detached uaudio0: detached uhub5: detached ugen4.2: <Microchip Tech USB2744> at usbus4 uhub5 on uhub2 uhub5: <Microchip Tech USB2744, class 9/0, rev 2.10/2.86, addr = 2> on usbus4 uhub5: MTT enabled uhub5: 4 ports with 4 removable, self powered random: harvesting attach, 8 bytes (4 bits) from uhub5 ugen4.3: <Dell Dell AC511 USB Soundbar> at usbus4 uaudio0 on uhub5 uaudio0: <Dell Dell AC511 USB Soundbar, class 0/0, rev = 1.10/1.10, addr 3> on usbus4 uaudio0: Play: 48000Hz, 2 ch, 16-bit S-LE PCM format, 2x8ms = buffer. uaudio0: Play: 44100Hz, 2 ch, 16-bit S-LE PCM format, 2x8ms = buffer. uaudio0: Record: 48000Hz, 2 ch, 16-bit S-LE PCM format, 2x8ms = buffer. uaudio0: Record: 44100Hz, 2 ch, 16-bit S-LE PCM format, 2x8ms = buffer. uaudio0: No MIDI sequencer.=20 pcm0: <USB audio> on uaudio0 pcm0: Mixer "vol" -> "none": child=3D0x00000010 pcm0: Mixer "pcm": parent=3D"vol" pcm0: Mixer "line": random: harvesting attach, 8 bytes (4 bits) from pcm0 uaudio0: HID volume keys found. random: harvesting attach, 8 bytes (4 bits) from uaudio0 This readout came after I was already logged in as root, some time = during the night when I and the screen were asleep. Very odd, however, it has now discovered the soundbar, albeit to what = extent I am quite unclear. ;-) Whenever these brain-scratchers appear, I find it is best to go at it = with documentation, advice, and a relaxed time-full approach, esp. since = I cannot turn on a debugger-tracer or have a file and setting BOM for = each port or even for the base. At Analogy (a less-than-250 person EDA company bought up by Synopsis) we = used to ship a release BOM that said exactly what a clean install would = change (and how) in terms of settings or dynamic files, where it would = add folders and files, and what those file sizes and types would be. We = also gave a checker that would verify the install process so handheld = tweaks could be made and installer issues reported. We did similar = things at Network General and Tektronix with robust documentation and = ways to change a generic install into the specific one your particular = platform would need in order to run (usually most heavily changed in the = I/O). So, I wonder what the process has been in terms of tools for that = or attempts at that w/r/t FreeBSD. Often, "open" team software hits the = wall w/r/t standards, documentation updating, process = verification/improvement.... I imagine it spreads out into millions of = hours of extra work by installers, much like the extra work required by = so many to write the same work-arounds for bad Microsoft IE code which = failed to follow standards like the rest of the browser community. Oh = well, you work with what you have until you and others are determined to = leap past a recurring issue with contributing yourselves. Maybe that = will be on my 2019 list after I finish my GNU self-directed health = analysis and simulation software. So, for now, does the above output = indicate a standardized way of saying "this is all okay and will work" = or is it like the famous "maybe gate" in board logic circuits? ;-) Oh, if anyone can suggest a few books w/r/t to actual FreeBSD output by = the base and port and upgrade processes, so I can decipher what "notes = to the logger" which will "speak to me" as well, I am all eyes and ears, = and hopefully, a learning brain.... best wishes, chris (aka "frank" as in Zappa and "fenderbender" as in parking lots and = guitars) frankfenderbender@council124.org=
